Product Introduction

Overview

The Texas Instruments OPA37GU is an ultra-low noise, high-precision monolithic operational amplifier. It is designed to offer exceptional performance in various precision applications. The OPA37GU features laser-trimmed thin-film resistors, which provide excellent long-term voltage offset stability and superior voltage offset compared to common zener-zap techniques. This amplifier is a decompensated version, requiring a closed-loop gain of 5 for stability, and it serves as an improved replacement for industry-standard OP-27 and OP-37 amplifiers.
