未来10年我国新能源车行业进入高速发展阶段，属于基础设施建设的充电桩也随之高速发展。交流充电桩中，输入输出电流通过采样后，通过运放放大信号，经由ADC转换传输至MCU实施检测。本文将推荐圣邦微（SGMICRO）推出的双路低噪声轨到轨输出运放 SGM8272，用于交流充电桩设计。

SGM8272封装图如下：

SGM8272在交流充电桩设计中有以下优势：

1、可在4.5V至36V单电源或±2.25V至±18V双电源下工作，满足多种应用场景；

2、输入失调电压0.6mV，满足信号的放大调理需求，有效降低小信号的放大误差；

3、压摆率5V/μs，可以实现快速电压转换；

4、静态电流低至150μA（典型值），有效降低待机功耗。

综上所述，圣邦微（SGMICRO）推出的双路低噪声轨到轨输出运放SGM8272，非常适合用于交流充电桩设计。
