OP37GH

Instrumentation, Op Amps, Buffer Amps Overview

The OP37GH is a low-noise, precision, high-speed operational amplifier from the Analog Devices OP37 series. It features a gain-bandwidth product of 63 MHz and a slew rate of 17 V/µs. The device offers an input offset voltage as low as 25 µV with a maximum drift of 0.2 µV/°C. Input bias current is typically 10 nA, and input voltage noise density is 3.5 nV/√Hz at 1 kHz. It operates on dual supplies up to ±22 V and functions within a temperature range of -55°C to +125°C.
