9 Application and Implementation

Note

Information in the following applications sections is not part of the TI component specification,

and TI does not warrant its accuracy or completeness. TI’s customers are responsible for

determining suitability of components for their purposes, as well as validating and testing their design

implementation to confirm system functionality.

9.1 Application Information

The OPAx310 family of rail-to-rail input and output operational amplifiers is specifically designed for high output

current applications. The devices operate from 1.5 V to 5.5 V, are unity-gain stable, and are also suitable for a

wide range of general-purpose applications. The class AB output stage is capable of driving small resistive loads

connected to any point between V+ and V– as long as the device is not forced into short circuit mode or thermal

shutdown mode. The input common-mode voltage range includes both rails and allows the OPAx310 series to

be used in many single-supply or dual supply configurations.
