【选型】为车载空调压缩机电机逆变电流采样选择CMOS运算放大器BU7244YFV-C，提供轨至轨输入/输出
车载空调压缩机电机逆变单元一般以隔离驱动芯片+IGBT单管设计实现低成本、小型化设计，其电机逆变的相电流（U、V、W）检测一般选用mΩ级shunt电阻（代表厂牌：ISA、TT、ROHM）+隔离放大器（Silicon labs的SI8920、SI8921）+模拟运放实现，典型应用电路框图参考如下图1所示。
图1：空调压缩机电机逆变驱动电路框图示意图
本文对shunt电阻和隔离放大器选型做详细介绍，主要是讨论下隔离放大器后级的模拟运放选型需要考虑哪些因素，参考如下：
1、轨至轨输入/输出（input/output Rail-to-Rail） ；
2、电源工作电压考量：单电源或者双电源均可，一般VS-=0V，VS+=5V或者更高，当然，电源电源越低越好；
3、 低的电源电流；
4、低偏置电流和失调电流；
5、 多路集成，便于实现紧凑型小型化设计；
6、宽工作温度范围：至少-40℃~105℃，高温达到125℃更好；
7、满足车规级AEC-Q100认证；
针对如上的设计需求，本文重点推荐ROHM（罗姆）推出的输入/输出轨到轨CMOS运算放大器BU7244YFV-C，采用SSOP-B14封装，封装尺寸W(Typ) x D(Typ) x H(Max)为5.00 mm x 6.40 mm x 1.35 mm
内部集成4路单运放，其实物图和pin脚定义示意图参考如下图2所示。
图2：ROHM（罗姆）CMOS运算放大器BU7244YFV-C实物图和pin脚定义示意图
下面从电性参数说明下推荐ROHM（罗姆）CMOS运算放大器BU7244YFV-C理由：
1、轨至轨输入/输出；
2、单电源工作电压范围1.8V ~ 5.5V，双电源工作电压范围±0.90V ~ ±2.75V，可满足低电源电压供电需求；
3、具有0.36mA低的典型供电电流，具有低功耗产品特性；
4、1pA典型输入失调电流和1pA典型输入偏置电流，具有高的产品精度，可实现高精度信号放大；
5、内部集成4路单路运放（CH1、CH2、CH3、CH4），仅需1颗即可，高度集成可实现紧凑型小型化设计
6、工作温度范围-40℃~125℃，可满足车载高温环境设计需求；
7、满足车规级AEC-Q100认证

运算放大器双极型和CMOS运算放大器其各自的输入偏置电流方向（极性）。
当输入为双极型晶体管时，输入段晶体管的基极电流为偏置电流。NPN为流入，PNP为流出。输入为MOSFET时，由于电流不会流入栅极，因此在输入端子和VDD间、输入端子和VSS间分别连接的静电保护元件漏电流流出和流入之差就是输入偏置电流。由于漏失的偏差，虽然有时会存在流入和流出的情况，但在室温中，绝对值为pA级。

运算放大器对于利用外接电阻进行放大电路增益设定，请告知当实测值与设计值不一致时可能的原因。
可能有几个原因看起来会使放大电路增益与设计值不一致。①偏置的影响 输入偏置电压以设定的电压增益倍产生输出偏置电压。增益越高，影响越大。如果不允许输入偏置电压标准值设定增益倍的输出电压偏差，请考虑采用低偏置运算放大器。此外，由于输入偏置电流和外接电阻乘积得到的电压会出现输出偏置，因此请尽量减小电阻值，考虑采用非反向输入和反向输入的输入端子的合成电阻值相一致，或是CMOS运算放大器。 ②最大输出电压的影响 有可能输入振幅较大而使输出振幅设定超过最大输出电压，导致输出嵌制。请注意当负载电流较大，电流能力不足时，最大输出电压也会下降。请用示波器确认输出波形。请修正电源电压及负载条件或者考虑使用输出全振幅运算放大器。 ③转换速率的影响 请用示波器确认输出波形。可输出的最大振幅Vpp和频率f的关系因转换速率SR受到限制，具有VppMAX=SR/（πf）的关系。请修正振幅或考虑使用转换速率较高的运算放大器。 ④运算放大器增益带宽积（GBW）的影响 如果输入频率×增益设定超过运算放大器的增益带宽积（GBW），增益将会低于设计值。请通过SPICE仿真等确认。请修正增益设定或考虑使用GBW较高的运算放大器。

CMOS运算放大器和双极型运算放大器的不同是什么？
CMOS运算放大器具有极小输入偏置电流（pA级）和低耗电量的特点。CMOS工艺的耐压低，适于低电源电压的应用。虽然双极型运算放大器的输入偏置电流、消耗电流比CMOS运算放大器多，但其具有易于提高耐压、低噪声、低偏置、宽频带的特点。
运算放大器产生输入偏置电流的原因。另外，请告知最大条件（温度及电源电压）。
输入偏置电流在双极型产品和CMOS产品中不同。双极型产品的输入偏置电流取决于输入段晶体管的基极电流和内部电流源，由于温度及电源电压，hFE受影响，输入偏置电流发生变化。在CMOS产品中，分别连接在输入端子和VDD之间、输入端子和VSS之间的静电保护元件漏电流流出和流入之差就是输入偏置电流，由于保护元件的漏失受温度及电源电压的影响而发生变化，因此该差分也会随之变化，从而导致输入偏置电流变化。详情请参考技术资料。温度及电源电压依赖性因各产品的电路结构而异，因此请确认Datasheet图及标准值。
