LT1990 Datasheet | Linear Technology

LT1990 ±250V Input Range G = 1, 10, Micropower, Difference Amplifier DESCRIPTIO The LT®1990 is a micropower precision difference amplifier with a very high mon mode input voltage range. It has pin selectable gains of 1 or 10. The LT1990 operates over a ±250V mon mode voltage range on a ±15V supply. The inputs are fault protected from mon mode voltage transients up to ±350V and differential voltages up to ±500V. The LT1990 is ideally suited for both high side and low side current or voltage monitoring. On a single 5V supply, the LT1990 has an adjustable 85V input range, 70dB min CMRR and draws less than 120µA supply current. The rail-to-rail output maximizes the dynamic range,...
