The LT1990ACS8#PBF is a micropower precision Difference Amplifier with a very high common mode input voltage range. It has pin selectable gains of 1 or 10. The LT1990 operates over a ±250V common-mode voltage range on a ±15V supply. The inputs are fault protected from common-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, especially important for single supplies as low as 2.7V.
● Rail-to-rail output
● 70dB Minimum common-mode rejection ratio
● Input protection to ±350V
● 0.28% Maximum gain error
● 82dB Minimum PSRR
● 120µA Micropower maximum supply current
