【应用】国产车规级零漂移运算放大器TPA5561Q-S5TR-S用于水阀执行器，输入温漂低至0.01μV/℃
随着新能源汽车技术的不断革新，整车热管理方案也由原来的分离式逐渐趋向于系统性和集中性，而水阀执行器作为其中不可或缺的一部分，起着控制水道通断的关键作用。一般来说，水阀执行器的电机为小功率的有刷直流电机，用MCU加电机驱动芯片即可，但有些电机驱动芯片不带电流采集和检测功能，这时就需要外加采样电阻和运放对电机的输入电流进行采样以及信号调理给到MCU的ADC。本文主要介绍国产品牌思瑞浦的零漂移运算放大器TPA5561Q-S5TR-S在水阀执行器产品中的部分应用优势，大致产品框图如下：
首先，对于水阀执行器来说本身就是热循环系统的重要零部件，其环境温度势必要比汽车其他零部件要高出一些，所以对于板上元器件选型就要特别注意温度对芯片的影响，而零漂移运算放大器TPA5561Q-S5TR-S输入温漂只有0.01μV/℃，即时温度变化很大它也依旧能够保证非常高的放大精度，大大提高了整体产品的可靠性。
其次，零漂移运算放大器TPA5561Q-S5TR-S的噪声也非常低，只有12Nv/√Hz（@1kHz），使得它的输出波形纹波较小，避免了后级ADC进行模数转换时产生误差，满足汽车产品对元器件高性能的要求。
最后，零漂移运算放大器PA5561Q-S5TR-S已经通过了AEC-Q100车规认证，适配很多整车厂对于芯片国产化的要求，极大地降低了供货风险以及芯片成本。
主要优势特点：
1、 超低温漂——0.01μV/℃，保证在恶劣工作条件下的放大精度
2、 低噪声12Nv/√Hz（@1kHz），满足汽车产品高性能要求
3、 已通过AEC-Q100认证，响应整车厂芯片国产化需求
