The INA157 is a high-gain, low-drift, high common-mode rejection, high input bandwidth difference amplifier.
The INA157 is a high‑slew‑rate difference amplifier offered in an SO‑8 surface‑mount package. It features low offset voltage (±500 µV max), low offset drift (2 µV/°C), low gain error (±0.05 %), a 3 MHz bandwidth and a 14 V/µs slew rate. The device operates from a wide supply range of +4 V to +18 V and draws only 2.4 mA quiescent current.
Designed for general‑purpose applications such as instrumentation amplifiers, differential receivers and current shunt monitors, the INA157 provides accurate gain (G = ½ or G = 2) with laser‑trimmed on‑chip resistors for high common‑mode rejection. Typical performance curves, pin configuration, and package information are included in the data sheet.
