These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.NOTES: 1.All voltage values, except differential voltages, are with respect to GND.2.Differential voltages are at IN+, with respect to IN−.3.Short circuits from outputs to V CC can cause excessive heating and eventual destruction.4.Maximum power dissipation is a function of T J (max), θJA , and T A . The maximum allowable power dissipation at any allowableambient temperature is P D = (T J (max) − T A )/θJA . Operating at the absolute maximum T J of 150°C can affect reliability.5.The package thermal impedance is calculated in accordance with JESD 51-7.6.Maximum power dissipation is a function of T J (max), θJC , and T C . The maximum allowable power dissipation at any allowable casetemperature is P D = (T J (max) − T C )/θJC . Operating at the absolute maximum T J of 150°C can affect reliability.7.The package thermal impedance is calculated in accordance with MIL-STD-883.LM193, LM293, LM293ALM393, LM393A, LM2903, LM2903V DUAL DIFFERENTIAL COMPARATORSSLCS005W − JUNE 1976 − REVISED JULY 20104POST OFFICE BOX 655303 •DALLAS, TEXAS 75265electrical characteristics at specified free-air temperature, V CC = 5 V (unless otherwise noted)LM193LM293LM393PARAMETERTEST CONDITIONS T A †MINTYP MAXMINTYP MAXUNITInput offset voltage V CC = 5 V to 30 V,14V 25°C 2525V IOInput offset voltageV O = 1.4 V,V IC = V IC(min)Full range 99mV Input offset current 14V 25°C 325550I IO Input offset current V O = 1.4 V Full range 100250nA Input bias current 14V 25°C −25−100−25−250I IBInput bias currentV O = 1.4 VFull range −300−400nACommon-mode25°C 0 toV CC − 1.50 toV CC − 1.5V ICRCommon mode input voltage range ‡Full range0 to V CC − 20 to V CC − 2VA VDLarge-signaldifferential-voltage amplification V CC = 15 V,V O = 1.4 V to 11.4 V,R L ≥ 15 k Ω to V CC 25°C 5020050200V/mV High-level V OH = 5 V,V ID = 1 V 25°C 0.10.150nA I OH High level output current V OH = 30 V,V ID = 1 V Full range 11µA Low-level4mA 1V 25°C 150400150400V OL Low level output voltage I OL = 4 mA,V ID = −1 V Full range 700700mV I OL Low-level output current V OL = 1.5 V,V ID = −1 V 25°C 66mA Supply current =∞V CC = 5 V 25°C 0.810.81I CCSupply currentR L = V CC = 30 VFull range2.52.5mA†Full range (MIN or MAX) for LM193 is −55°C to 125°C, for LM293 is 25°C to 85°C, and for LM393 is 0°C to 70°C.

LM393资料-lm393中文资料-lm393 比较器参数-lm393是什么
LM393 是双电压比较器集成电路。
该电路的特点如下：工作电源电压范围宽，单电源、双电源均可工作，单电源：2～36V，双电源:±1～±18V；消耗电流小，Icc=0.8mA；输入失调电压小，VIO=±2mV；共模输入电压范围宽，Vic=0～Vcc-1.5V；输出与TTL，DTL，MOS，CMOS 等兼容；输出可以用开路集电极连接“或”门；采用双列直插8 脚塑料封装（DIP8）和微形的双列8 脚塑料封装（SOP8）LM393内部结构图LM393引脚功能排列表：引出端序号功能符号引出端序号.功能符号1输出端1OUT15正向输入端2 1N+(2)2反向输入端1 1N-(1)6反向输入端2 1N-(2)3正向输入端1 1N+(1)7输出端2OUT24地GND8电源VCCLM393主要参数表：参数名称符号数值单位电源电压VCC±18 或36V差模输入电压VID±36V共模输入电压VI-0.3～VCCV功耗Pd570mW工作环境温度Topr0 to +70℃贮存温度Tstg-65 to 150℃电特性（除非特别说明，VCC=5.0V，Tamb=25℃）参数名称符号测试条件最小典型最大单位输入失调电压VIOVCM=0 to VCC-1.5 VO(P)=1.4V, Rs=0-±1.0±5.0mV输入失调电流IIO--±5±50nA输入偏置电流Ib--65250nA共模输入电压VIC--VCC-1.5V静态电流ICCQ RL=∞-0.61.0mARL=∞,Vcc=30V-0.82.5mA电压增益AVVCC=15V, RL＞15kΩ-200-V/mV灌电流lsinkVi(-)＞1V, Vi(+)=0V, Vo(p)＜1.5V616-mA输出漏电流IOLEVi(-)=0V, Vi(+)=1V, VO=5V-0.1-nA应用说明:LM393是高增益,宽频带器件,象大多数比较器一样,如果输出端到输入端有寄生电容而产生耦合,则很容易产生振荡.这种现象仅仅出现在当比较器改变状态时,输出电压过渡的间隙.电源加旁路滤波并不能解决这个问题,标准PC板的设计对减小输入—输出寄生电容耦合是有助的.减小输入电阻至小于10K 将减小反馈信号,而且增加甚至很小的正反馈量(滞回1.0~10mV)能导致快速转换,使得不可能产生由于寄生电容引起的振荡.除非利用滞后,否则直接插入IC并在引脚上加上电阻将引起输入—输出在很短的转换周期内振荡,如果输入信号是脉冲波形,并且上升和下降时间相当快,则滞回将不需要.比较器的所有没有用的引脚必须接地.LM393偏置网络确立了其静态电流与电源电压范围2.0~30V无关.通常电源不需要加旁路电容。

This current is essentially constant, independent of the output state,therefore, no loading changes will exist on the input lines.6.Input common mode of either input should not be permitted to go more than 0.3 V negative of ground or minus supply. The upper limit ofcommon mode range is V CC −1.5 V.7.Response time is specified with a 100 mV step and 5.0 mV of overdrive. With larger magnitudes of overdrive faster response times areobtainable.8.The comparator will exhibit proper output state if one of the inputs becomes greater than V CC, the other input must remain within the commonmode range. The low input state must not be less than −0.3 V of ground or minus supply.LM293/393LM2903Figure 2. Input Bias Current versusPower Supply Voltage Figure 3.

This gives the device oscillation tendencies if the outputs are capacitively coupled to the inputs via stray capacitance. This oscillation manifests itself during output transitions (V OL to V OH ). To alleviate this situation, input resistors <10 k W should be used.The addition of positive feedback (<10mV) is also recommended. It is good design practice to ground all unused pins.Differential input voltages may be larger than supply voltage without damaging the comparator’s inputs. V oltages more negative than −0.3 V should not be used.Figure 8. Zero Crossing Detector(Single Supply)Figure 9. Zero Crossing Detector(Split Supply)Figure 10.

《lm339应用电路》
图1所示为一最简单的电压比较器，UR为参考电压，加在运放的同相的输入端，输入电压ui加在反相的输入端。
〈电压比较器原理原理图>
(a）电路图（b）传输特性当ui＜UR时，运放输出高电平，稳压管Dz反向稳压工作.输出端电位被其箝位在稳压管的稳定电压UZ,即 uO＝UZ
当ui＞UR时，运放输出低电平，DZ正向导通，输出电压等于稳压管的正向压降UD，即 uo＝－UD
因此，以UR为界,当输入电压ui变化时，输出端反映出两种状态，高电位和低电位。
表示输出电压与输入电压之间关系的特性曲线，称为传输特性.图3－1（b)为(a）图比较器的传输特性。
常用的电压比较器有过零电压比较器、具有滞回特性的过零比较器、滞回电压比较器,窗口（双限）电压比较器。
LM339常用来构成各种电压比较器
集成电压比较器简介：
作用：可将模拟信号转换成二值信号,即只有高电平和低电平两种状态的离散信号。
应用：作为模拟电路和数字电路的接口电路.
特点：比集成运放的开环增益低，失调电压大，共模抑制比小;但其响应速度快，传输延迟时间短,而且不需外加限幅电路就可直接驱动TTL、CMOS和ECL等集成数字电路；有些芯片带负载能力很强，还可直接驱动继电器和指。

LM393双电压比较器
LM393双电压比较器LM393 是双电压比较器集成电路。
该电路的特点如下:比较器数:2工作温度范围:0?C to +70?CSVHC(高度关注物质):No SVHC (18-Jun-2010)器件标号:393通道数:2逻辑功能号:393工作电源电压范围宽，单电源、双电源均可工作，单电源: 2, 36V，双电源:?1,?18V;消耗电流小， ICC=0.8mA;输入失调电压小， VIO=?2mV;共模输入电压范围宽， VIC=0,VCC-1.5V;输出与TTL，DTL，MOS，CMOS 等兼容;输出可以用开路集电极连接“或”门;采用双列直插8 脚塑料封装(DIP8)和微形的双列8 脚塑料封装(SOP8)。
表面安装器件:表面安装LM393内部结构图:采用双列直插8 脚塑料封装(DIP8)和微形的双列8 脚塑料封装(SOP8)应用说明:LM393是高增益,宽频带器件，象大多数比较器一样，如果输出端到输入端有寄生电容而产生耦合，则很容易产生振荡。
这种现象仅仅出现在当比较器改变状态时，输出电压过渡的间隙，电源加旁路滤波并不能解决这个问题，标准PC板的设计对减小输入—输出寄生电容耦合是有助的。
减小输入电阻至小于10K将减小反馈信号，而且增加甚至很小的正反馈量(滞回1.0~10mV)能导致快速转换,使得不可能产生由于寄生电容引起的振荡，除非利用滞后，否则直接插入IC(集成电路板integrated circuit，缩写:IC) 并在引脚上加上电阻将引起输入—输出在很短的转换周期内振荡，如果输入信号是脉冲波形，并且上升和下降时间相当快，则滞回将不需要。
比较器的所有没有用的引脚必须接地。
LM393偏置网络确立了其静态电流与电源电压范围 2.0~30V无关。
通常电源不需要加旁路电容。
差分输入电压可以大于Vcc并不损坏器件，保护部分必须能阻止输入电压向负端超过-0.3V。
LM393的输出部分是集电极开路，发射极接地的 NPN输出晶体管，可以用多集电极输出提供或OR ing主要功能:输出负载电阻能衔接在可允许电源电压范围内的任何电源电压上，不受 Vcc端电压值的限制.此输出能作为一个简单的对地SPS开路(当不用负载电阻没被运用)，输出部分的陷电流被可能得到的驱动和器件的β值所限制.当达到极限电流(16mA)时，输出晶体管将退出而且输出电压将很快上升。

This current is essentially constant, independent of the output state,therefore, no loading changes will exist on the input lines.7.Input common mode of either input should not be permitted to go more than 0.3 V negative of ground or minus supply. The upper limit ofcommon mode range is V CC −1.5 V.8.Response time is specified with a 100 mV step and 5.0 mV of overdrive. With larger magnitudes of overdrive faster response times areobtainable.9.The comparator will exhibit proper output state if one of the inputs becomes greater than V CC, the other input must remain within the commonmode range. The low input state must not be less than −0.3 V of ground or minus supply.LM293/393LM2903Figure 6. Power Supply Current versusPower Supply Voltage Figure 7.

This gives the device oscillation tendencies if the outputs are capacitively coupled to the inputs via stray capacitance. This oscillation manifests itself during output transitions (V OL to V OH ). To alleviate this situation, input resistors <10 k W should be used.The addition of positive feedback (<10mV) is also recommended. It is good design practice to ground all unused pins.Differential input voltages may be larger than supply voltage without damaging the comparator’s inputs.
