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.
