LT1990IS8#PBF

LT1990 is a micropower precision difference amplifier with a very high common mode input voltage range. It has pin selectable gains of 1 or 10. 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 widely used in application such as battery cell voltage monitoring, high voltage current sensing, signal acquisition in noisy environments, input protection, fault protected front ends, level sensing, isolation etc.
