概述
AD8232是一款用于ECG及其他生物电测量应用的集成信 号调理模块。该器件设计用于在具有运动或远程电极放 置产生的噪声的情况下提取、放大及过滤微弱的生物电 信号。该设计使得超低功耗模数转换器(ADC)或嵌入式 微控制器能够轻松地采集输出信号。 AD8232采用双极点高通滤波器来消除运动伪像和电极 半电池电位。该滤波器与仪表放大器结构紧密耦合，可 实现单级高增益及高通滤波，从而节约了空间和成本。 AD8232采用一个无使用约束运算放大器来创建一个三 极点低通滤波器，消除了额外的噪声。用户可以通过选 择所有滤波器的截止频率来满足不同类型应用的需要。

为了提高系统线路频率和其他不良干扰的共模抑制性 能，AD8232内置一个放大器，用于右侧驱动(RLD)等受 驱导联应用。 AD8232包含一项快速恢复功能，可以减少高通滤波器 原本较长的建立长尾现象。如果放大器轨电压发生信号 突变(如导联脱离情况)，AD8232将自动调节为更高的滤 波器截止状态。该功能让AD8232可以实现快速恢复， 因而在导联连接至测量对象的电极之后能够尽快取得有 效的测量值。 AD8232采用4 mm × 4 mm、20引脚LFCSP封装。额定温 度范围为0°C至70℃，能在-40℃至+85℃的范围内工作。

效率输出晶体管的开关工作方式决定了D 类放大器的高效率。
在Ｄ类放大器中，输出晶体管就像是一个电流调整开关，切换过程中消耗的额外功率基本可以忽略不计。
输出级相关的功率损耗主要是由MOSFET 导通电阻与电源电流产生的I R 。
升压启动后CS8323S 的效率可达72%。
CS8323S 无需滤波器的PWM 调制结构减少了外部元件数目，PCB 面积和系统成本，并且简化了设计。
芯片内置了过流保护，过热保护和欠压保护功能，这些功能保证了芯片在异常的工作条件下关断芯片，有效地保护了芯片不被损坏，当异常条件消除后，C S8323S 有自恢复功能可以让芯片重新工作。
2无需滤波器CS8323S 采用无需滤波器的PWM 调制方式，省去了传统D 类放大器的LC 滤波器，提高了效率，为便携式设备的音频子系统提供了一个更小面积，更低成本的实现方案。
Pop & Click 抑制CS8323S 内置专有的时序控制电路,实现全面的Pop & Click 抑制,可以有效地消除系统在上电,下点,Wake up 和Shutdown 操作时可能会出现的瞬态噪声。
保护电路CS8323S 在应用的过程中,当芯片发生输出管脚和电源或地短路，或者输出之间的短路故障时,过流保护电路会关断芯片以防止芯片被损坏。
短路故障消除后,CS8323S 自动恢复工作。
当芯片温度过高时,芯片也会被关断。
温度下降后,CS8323S 可以继续正常工作。

·为了避免短路和潜在的生命危险，决不能将钳口夹在对地额定电压超过 600V 的电路或裸线上。 ·钳口只能连接到断路器的次级，这样断路器才可以防止因短路而发生的意外事故；决不能连 接到断路器的初级，因为一但发生短路的意外事故将无法得到保护。 ·先将电压线连接到仪器，再给被测线路通电。遵守以下事项以避免电击和短路：

The new PWM control circuit automatically changes the duty ratio from 0% to 83% according to the current load, offering products of a wide range, high efficiency. A step-up switching regulator isconstructed by externally connecting only a coil, a capacitor and a diode to the S-8323 Series. This feature, along with its small package and low current consumption, makes the S-8323 Series ideal for the power supply of portable equipment. For applications requiring a high output current, products used with an external transistor (S-8327 Series) are also available.FeaturesApplicationsLow voltage operation: 0.9 V (I OUT = 1mA)Power supplies for portable equipment such as Low current consumption :pagers, handy calculators, and remote controllers During operation: 17.2µA (typ.)Constant voltage power supplies for cameras,(V OUT = 3 V, 50 kHz)video equipment, and communications equipment During shutdown : 0.5µA (max.)Power supply for microcomputersDuty ratio:Built-in PWM control circuitExternal parts:coil, diode, and capacitor only(a transistor is needed for the S-8327 Series.)

S-8323/8327 Series is a step-up switching regulator using a pulse width modulation method (PWM) and DC/DC converter and features a low current consumption.In conventional PFM DC/DC converters, pulses are skipped at low output load current, causing fluctuation in ripple frequency of the output voltage, with the result of increase in ripple voltage.The S-8323/8327 series operates with the PWM control which changes the pulse width duty from 0% to 83% according to the load current.The ripple voltage generated from switching can be removed easily through the filter because the switching frequency is constant.The built-in soft start circuit controls a rush current and overshoot of the output voltage when powering on or the ON/OFF terminal turns to “H” level.Shutdown pin:Stops or starts step-up operation.(Only for SOT-23-5 package products of A and B Series.)Turning the shutdown pin low stops operation of all the internal circuits and reduces current consumption significantly. DO NOT use the shutdown pin in floating state because it has a structure shown in Figure 4and is not pulled up or pulled down internally. DO NOT apply voltage of between 0.3 V and 0.75 V to the shutdown pin because applying such voltage increases the current consumption. If the shutdown pin is not used, connect it to V OUT pin.The shutdown pin doesn’t have hysteresis.Shutdown pinCR oscillationcircuit Output voltage “H”Operation Fixed “L”Stop~V IN *Figure 4ON/OFFV OUTV SS*Voltage obtained by extracting the voltage drop due to DC resistance of the inductor and the diode forward voltage from V IN.Figure 5+-+-OSC C OUTCONTM1V INLDiON/OFFV OUTThe following are basic equations [(1) through (7)] of the step-up switching regulator (see Figure 5.)Voltage at CONT pin the moment M1 is turned ON (current I L flowing through L is zero):The change in I L over time:Integration of the above equation (I L ):I L flows while M1 is ON (t ON ). The time of t ON is determined by the oscillation frequency of the OSC.The peak current (I PK ) after t ON :The energy stored in L is represented with 1/2 L (I PK )2.When M1 is turned OFF (t OFF ), the energy stored in L is transmitted through a diode to the output capacitor. Then reverse voltage (V L ) is generated.V L = (V OUT +V D ) - V IN (5)(V D : Diode forward voltage)The voltage at CONT pin rises only by the voltage corresponding to V OUT +V D .The change in the current flowing through the diode into V OUT during t OFF :Integration of the above equation is as follows:During t ON , the energy is stored in L and is not transmitted to V OUT . When receiving output current (I OUT ) from V OUT , the energy of the capacitor (C OUT ) is consumed. As a result, the pin voltage of C OUT is reduced, and goes to the lowest level after M1 is turned ON (t ON ). When M1 is turned OFF, the energy stored in L is transmitted through the diode to C OUT , and the voltage of C OUT rises drastically. V OUT is a time function that indicates the maximum value (ripple voltage: V P-P ) when the current flowing through the diode into V OUT and load current (I OUT ) match.Next, the ripple voltage is found out as follows:I OUT vs t 1 (time) from when M1 is turned OFF (after t ON ) to when V OUT reaches the maximum level:When M1 is turned ON (after t OFF ), IL=0 (when the energy of the inductor is completely transmitted).
