7 Detailed Description

7.1 Overview

The OPA320-Q1 and OPA2320-Q1 (OPAx320-Q1) operational amplifiers (op amps) are unity-gain stable and

operate on a single-supply voltage (1.8 V to 5.5 V), or a split supply voltage (±0.9 V to ±2.75 V), making these

devices highly versatile and easy to use. The OPAx320-Q1 amplifiers are fully specified from 1.8 V to 5.5 V and

over the extended temperature range of –40°C to +125°C. Parameters that can exhibit variance with regard to

operating voltage or temperature are presented in the Typical Characteristics section.
