8.1 Overview
The OPA317-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 OPA317 series 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 ideal for driving sampling analog-to-digital converters
(ADCs).

8.3 Feature Description
8.3.1 Operating Voltage
The OPA317-Q1 series of operational amplifiers can be used with single or dual supplies from an operating
range of V_S = 1.8 V (±0.9 V) up to 5.5 V (±2.75 V).
CAUTION
Supply voltages greater than 7 V can permanently damage the device.
See the Absolute Maximum Ratings table. Key parameters that vary over the supply voltage or temperature
range are shown in the Typical Characteristics section.
