LT1990IS8 Products

The LT1990IS8 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 LT1990IS8 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 LT1990IS8 is ideally suited for both high side and low side current or voltage monitoring.

On a single 5V supply, the LT1990IS8 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.

The LT1990IS8 is specified for single 3V, 5V and ±15V supplies over both commercial and industrial temperature ranges. The LT1990IS8 is available in the 8-pin SO package.
