7.1 Overview

The OPAx397 is a family of low offset, low-noise e-trim operational amplifiers (op amps) that uses a proprietary offset trim technique. These op amps offer ultra-low input offset voltage and drift and achieve excellent input and output dynamic linearity. The OPAx397 operate from 1.7 V to 5.5 V, are unity-gain stable, and are designed for a wide range of general-purpose and precision applications.

The amplifiers feature state-of-the-art CMOS technology and advanced design features that help achieve extremely low input bias current, wide input and output voltage ranges, high loop gain, and low, flat output impedance in small package options. The OPAx397 strengths also include 13‑MHz bandwidth, 4.4‑nV/√Hz noise spectral density, and low 1/f noise. These features make the OPAx397 an exceptional choice for interfacing with sensors, photodiodes, and high-performance analog-to-digital converters (ADCs).
