vs.Time20071515LMP2011Single/LMP2012Dual/LMP2014Quad9Application InformationTHE BENEFITS OF LMP201XNO1/f NOISEUsing patented methods,the LMP201X eliminates the1/fnoise present in other amplifiers.That noise,which in-creases as frequency decreases,is a major source of mea-surement error in all DC-coupled measurements.Low-frequency noise appears as a constantly-changing signal inseries with any measurement being made.As a result,evenwhen the measurement is made rapidly,this constantly-changing noise signal will corrupt the result.The value of thisnoise signal can be surprisingly large.For example:If aconventional amplifier has a flat-band noise level of10nV/and a noise corner of10Hz,the RMS noise at0.001Hz is1µV/.This is equivalent to a0.50µV peak-to-peak error,in the frequency range0.001Hz to1.0Hz.In acircuit with a gain of1000,this produces a0.50mV peak-to-peak output error.This number of0.001Hz might appearunreasonably low,but when a data acquisition system isoperating for17minutes,it has been on long enough toinclude this error.In this same time,the LMP201X will onlyhave a0.21mV output error.This is smaller by2.4x.Keepin mind that this1/f error gets even larger at lower frequen-cies.At the extreme,many people try to reduce this error byintegrating or taking several samples of the same signal.This is also doomed to failure because the1/f nature of thisnoise means that taking longer samples just moves themeasurement into lower frequencies where the noise level iseven higher.The LMP201X eliminates this source of error.The noiselevel is constant with frequency so that reducing the band-width reduces the errors caused by noise.Another source of error that is rarely mentioned is the errorvoltage caused by the inadvertent thermocouples createdwhen the common"Kovar type"IC package lead materialsare soldered to a copper printed circuit board.These steel-based leadframe materials can produce over35µV/˚C whensoldered onto a copper trace.This can result in thermo-couple noise that is equal to the LMP201X noise when thereis a temperature difference of only0.0014˚C between thelead and the board!For this reason,the lead-frame of the LMP201X is made ofcopper.This results in equal and opposite junctions whichcancel this effect.The extremely small size of the SOT-23package results in the leads being very close together.Thisfurther reduces the probability of temperature differencesand hence decreases thermal noise.OVERLOAD RECOVERYThe LMP201X recovers from input overload much fasterthan most chopper-stabilized op amps.Recovery from driv-ing the amplifier to2X the full scale output,only requiresabout40ms.Many chopper-stabilized amplifiers will takefrom250ms to several seconds to recover from this sameoverload.This is because large capacitors are used to storethe unadjusted offset voltage.The wide bandwidth of the LMP201X enhances performancewhen it is used as an amplifier to drive loads that injecttransients back into the output.ADCs(Analog-to-Digital Con-verters)and multiplexers are examples of this type of load.To simulate this type of load,a pulse generator producing a1V peak square wave was connected to the output through a10pF capacitor.(Figure1)The typical time for the output torecover to1%of the applied pulse is80ns.To recover to0.1%requires860ns.This rapid recovery is due to the widebandwidth of the output stage and large total GBW.NO EXTERNAL CAPACITORS REQUIREDThe LMP201X does not need external capacitors.This elimi-nates the problems caused by capacitor leakage and dielec-tric absorption,which can cause delays of several secondsfrom turn-on until the amplifier’s error has settled.MORE BENEFITSThe LMP201X offers the benefits mentioned above andmore.It has a rail-to-rail output and consumes only950µA ofsupply current while providing excellent DC and AC electricalperformance.In DC performance,the LMP201X achieves130dB of CMRR,120dB of PSRR and130dB of open loopgain.In AC performance,the LMP201X provides3MHz ofgain-bandwidth product and4V/µs of slew rate.HOW THE LMP201X WORKSThe LMP201X uses new,patented techniques to achieve thehigh DC accuracy traditionally associated with chopper-stabilized amplifiers without the major drawbacks producedby chopping.The LMP201X continuously monitors the inputoffset and corrects this error.The conventional choppingprocess produces many mixing products,both sums anddifferences,between the chopping frequency and the incom-ing signal frequency.This mixing causes large amounts ofdistortion,particularly when the signal frequency approachesthe chopping frequency.Even without an incoming signal,the chopper harmonics mix with each other to produce evenmore trash.If this sounds unlikely or difficult to understand,look at the plot(Figure2),of the output of a typical(MAX432)chopper-stabilized op amp.This is the output when there isno incoming signal,just the amplifier in a gain of-10with theinput grounded.The chopper is operating at about150Hz;the rest is mixing products.Add an input signal and the noisegets much pare this plot with Figure3of theLMP201X.This data was taken under the exact same con-ditions.The auto-zero action is visible at about30kHz butnote the absence of mixing products at other frequencies.Asa result,the LMP201X has very low distortion of0.02%andvery low mixing products.20071516FIGURE1.LMP211Single/LMP212Dual/LMP214Quad10Application Information(Continued)INPUT CURRENTSThe LMP201X’s input currents are different than standard bipolar or CMOS input currents in that it appears as a current flowing in one input and out the other.Under most operating conditions,these currents are in the picoamp level and will have little or no effect in most circuits.These currents tend to increase slightly when the common-mode voltage is near the minus supply.(See the typical curves.)At high temperatures such as85˚C,the input currents become larger,0.5nA typical,and are both positive except when the V CM is near V−.If operation is expected at low common-mode voltages and high temperature,do not add resistance in series with the inputs to balance the impedances.Doing this can cause an increase in offset voltage.A small resistance such as1 kΩcan provide some protection against very large transients or overloads,and will not increase the offset significantly.PRECISION STRAIN-GAUGE AMPLIFIERThis Strain-Gauge amplifier(Figure4)provides high gain (1006or~60dB)with very low offset and ing the resistors’tolerances as shown,the worst case CMRR will be greater than108dB.The CMRR is directly related to the resistor mismatch.The rejection of common-mode error,at the output,is independent of the differential gain,which is set by R3.The CMRR is further improved,if the resistor ratio matching is improved,by specifying tighter-tolerance resis-tors,or by trimming.Extending Supply Voltages and Output Swing by Using a Composite Amplifier Configuration:In cases where substantially higher output swing is required with higher supply voltages,arrangements like the ones shown in Figure5and Figure6could be used.These configurations utilize the excellent DC performance of the LMP201X while at the same time allow the superior voltage and frequency capabilities of the LM6171to set the dynamic performance of the overall amplifier.For example,it is pos-sible to achieve±12V output swing with300MHz of overall GBW(A V=100)while keeping the worst case output shift due to V OS less than4mV.The LMP201X output voltage is kept at about mid-point of its overall supply voltage,and its input common mode voltage range allows the V-terminal to be grounded in one case(Figure5,inverting operation)and tied to a small non-critical negative bias in another(Figure6, non-inverting operation).Higher closed-loop gains are also possible with a corresponding reduction in realizable band-width.Table1shows some other closed loop gain possibili-ties along with the measured performance in each case.20071517 FIGURE2.20071504 FIGURE3.20071518FIGURE4.LMP2011Single/LMP2012Dual/LMP2014Quad11Application Information(Continued)TABLE posite

the measured output peak-to-peak noise,the following relationship holds between output noise voltage,e n p-p,for different closed-loop gain,A V ,settings,where −3dB Bandwidth is BW:It should be kept in mind that in order to minimize the output noise voltage for a given closed-loop gain setting,one could minimize the overall bandwidth.As can be seen from Equa-tion 1above,the output noise has a square-root relationship to the Bandwidth.In the case of the inverting configuration,it is also possible to increase the input impedance of the overall amplifier,by raising the value of R1,without having to increase the feed-back resistor,R2,to impractical values,by utilizing a "Tee"network as feedback.See the LMC6442data sheet (Appli-cation Notes section)for more details on this.20071519FIGURE

amplifier stage imme-diately before the input of an ADC (Analog-to-Digital Con-verter),whether AC or DC coupled.See Figure 7and Figure 8.This is because of the following important characteristics:A)Very low offset voltage and offset voltage drift over timeand temperature allow a high closed-loop gain setting without introducing any short-term or long-term errors.For example,when set to a closed-loop gain of 100as the analog input amplifier for a 12-bit A/D converter,the overall conversion error over full operation temperature and 30years life of the part (operating at 50˚C)would be less than 5LSBs.B)Fast large-signal settling time to 0.01%of final value (1.4µs)allows 12bit accuracy at 100KH Z or more sampling rate.C)No flicker (1/f)noise means unsurpassed data accuracyover any measurement period of time,no matter how long.Consider the following op amp performance,based on a typical low-noise,high-performance commercially-available device,for comparison:Op amp flatband noise =8nV/1/f corner frequency =100Hz A V =2000Measurement time =100sec Bandwidth =2HzThis example will result in about 2.2mV PP (1.9LSB)of output noise contribution due to the op amp alone,com-pared to about 594µV PP (less than 0.5LSB)when that op amp is replaced with the LMP201X which has no 1/f contribution.If the measurement time is increased from 100seconds to 1hour,the improvement realized by using the LMP201X would be a factor of about 4.8times (2.86mV PP compared to 596µV when LMP201X is used)mainly because the LMP201X accuracy is not compromised by increasing the observation time.D)Copper leadframe construction minimizes any thermo-couple effects which would degrade low level/high gain data conversion application accuracy (see discussion under "The Benefits of the LMP201X"section above).E)Rail-to-Rail output swing maximizes the ADC dynamicrange in 5-Volt single-supply converter applications.Be-low are some typical block diagrams showing the LMP201X used as an ADC amplifier (Figure 7and Figure 8).20071522FIGURE 8.LMP2011Single/LMP2012Dual/LMP2014Quad13Physical Dimensionsinches (millimeters)unless otherwise noted5-Pin

NXPLPC111x芯片中文手册―11带SSP的SPI01

up .w hd 1. 如何阅读本章所有 LPC111x 系列中的 SPI 模块均相同。

第二个 SPI 模块, SPI1,只存在于LQFP48和 PLCC44封装上,在 HVQFN33封装上则没有。

注释:两个 SPI 模块都包含全部的 SSP 特征集,所有相关寄存器都使用 SSP 前缀命名。

2. 特性? 兼容 Motorola SPI 、 4线 TI SSI 和美国国家半导体公司的 Microwire 总线。

? 同步串行通信。

? 支持主机和从机操作。

? 收发均有 8帧 FIFO 。

?每帧有 4-16位数据。

3. 基本描述SPI/SSP是一个同步串行端口 (SSP控制器,可控制 SPI 、 4线 SSI 和 Microwire 总线。

它可以与总线上的多个主机和从机相互作用。

在数据传输过程中,总线上只能有一个主机与一个从机进行通信。

原则上数据传输是全双工的, 4~16位帧的数据由主机发送到从机或由从机发送到主机。

但实际上,大多数情况下只有一个方向上的数据流包含有意义的数据。

LPC111x 系列处理器有两个 SPI/同步串行端口控制器。

u d u UM10398Semiconductors LPC1100开发,尽在第 11章 :LPC111x 带有 SSP 的 SPI0/1 4. 引脚描述表 161622. SPI 引脚描述SCK0/1I/OSCK CLK SK 串行时钟。

SCK/CLK/SK是用来同步数据传输的时钟信号。

它由主机驱动,从机接收。

当使用 SPI 接口时,时钟可编程为高电平有效或低电平有效,否则总是高电平有效。

SCK 仅在数据传输过程中切换。

在其它时间里, SPI/SSP接口保持无效状态或不驱动它(使其处于高阻态。

SSEL0/1I/OSSEL FS CS 帧同步 /从机选择。

当 SPI/SSP接口是总线主机时,它在串行数据启动前驱动该信号为有效状态。

在数据发送出去之后又将该信号恢复为无效状态。
