8 Detailed Description

8.1 Overview

The OPAx607 devices are low-noise, rail-to-rail output (RRO) operational amplifiers (op amp). The devices

operate from a supply voltage of 2.2 V to 5.5 V. The input common-mode voltage range also extends

down to the negative rail allowing the OPAx607 to be used in most single-supply applications. Rail-to-rail

output swing significantly increases dynamic range, especially in low-supply, voltage-range applications, which

results in complete usage of the full-scale range of the consecutive analog-to-digital converters (ADCs).

The decompensated architecture allows for a favorable tradeoff of low-quiescent current for a very-high gain-

bandwidth product (GBW) and low-distortion performance in high-gain applications.
