Abstract

This paper describes the implementation of a 60V programmable-gain amplifier (PGA) with ±10V differential input range and a 5V output compatible with many commercially available ADCs. While there is a wide range of possible applications, this design is particularly well suited for ±24V supply industrial process control applications, where small voltage signals need to be acquired in the presence of very large common-mode voltages.

60V电容增益27nV/√Hz 137dB CMRR PGA,输入±10V
本文介绍了一种60V可编程增益放大器(PGA)的实现,其差分输入范围为±10V,输出为5V,与许多市售adc兼容。虽然可能的应用范围很广,但该设计特别适合于±24V电源工业过程控制应用,需要在非常大的共模电压存在下获取小电压信号。
