8.1 Overview

The OPAx375 family is an ultra low-noise, rail-to-rail output operational amplifier. The device operates from a supply voltage of 2.25 V to 5.5 V (OPA375) and 1.7 V to 5.5 V (OPA2375 and OPA4375), are unity-gain stable, and suitable for a wide range of general-purpose applications. The input common-mode voltage range includes the negative rail and allows the OPAx375 op amp family to be used in most single-supply applications. Rail-to-rail output swing significantly increases dynamic range, especially in low-supply applications, and makes it suitable for many audio applications and driving sampling analog-to-digital converters (ADCs).
