Product Summary

The INA157U is a high slew rate, G = 1/2 or G = 2 difference amplifier consisting of a precision op amp with a precision resistor network. The on-chip resistors are laser trimmed for accurate gain and high common-mode rejection. Excellent TCR tracking of the resistors maintains gain accuracy and common-mode rejection over temperature. The input common-mode voltage range extends beyond the positive and negative supply rails. It operates on ±4V to ±18V supplies. The applications of the INA157U are (1)differential input amplifier; (2)instrumentation amplifier building block; (3)g = 1/2 amplifier; (4)g = 2 amplifier; (5)differential current receiver; (6)voltage-controlled current source; (7)ground loop eliminator; (8)current shunt monitor.
