LT1990IMS8-10#PBF

LT1990IMS8-10#PBF is a micropower precision difference amplifier with a very high common mode input voltage range and a fixed gain of 10 and 100KHz bandwidth. This device operates over a ±250V common mode voltage range on a ±15V supply. The inputs are fault-protected from common mode voltage transients upto ±350V and differential voltages up to ±500V. It is ideally suited for both high-side and low-side current or voltage monitoring. It is used in applications such as battery cell voltage monitoring, high voltage current sensing, signal acquisition in noisy environments, input protection, fault-protected front ends, level sensing, and isolation.
