The LT®1990-10 is a micropower precision difference amplifier with a very high common mode input voltage range, a fixed gain of 10 and 100kHz bandwidth. The LT1990-0 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 differentialvoltages up to ±500V. The LT1990-10 is ideally suited for both high side and low side current or voltage monitoring.
On a single 5V supply, the LT1990-10 has an adjustable 85V input range, 60dB min CMRR and draws less than 180µA supply current. The rail-to-rail output maximizes the dynamic range, especially important for single supplies as low as 2.7V.
The LT1990-10 is specified for single 3V, 5V and ±15V supplies over the industrial temperature range.
The LT1990-10 is available in the 8-pin SO and pin FMEA compatible MSOP packages.
