8 Detailed Description

8.1 Overview

The TLVx316-Q1 is a family of low-power, rail-to-rail input and output operational amplifiers. These devices

operate from 1.8 V to 5.5 V, are unity-gain stable, and are suitable for a wide range of general-purpose

applications. The class AB output stage is capable of driving

≤ 10-kΩ loads connected to any point between V+

and ground. The input common-mode voltage range includes both rails and allows the TLVx316-Q1 to be used in

virtually any single-supply application. Rail-to-rail input and output swing significantly increases dynamic range,

especially in low-supply applications, and makes them suitable for driving sampling analog-to-digital converters

(ADCs).

The TLVx316-Q1 features 10-MHz bandwidth and 6-V/μs slew rate with only 400-μA supply current per channel,

providing good ac performance at very-low-power consumption. DC applications are well served with a very-low

input noise voltage of 12 nV/

√Hz at 1 kHz, low input bias current (5 pA), and an input offset voltage of 0.5 mV

(typical).
