8 Application and Implementation
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. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The LMV3xxA is a family of low-power, rail-to-rail output operational amplifiers specifically designed for portable
applications. The devices operate from 2.5 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 less than or equal to 10-kΩ loads
connected to any point between V+ and V–. The input common-mode voltage range includes the negative rail,
and allows the LMV3xxA to be used in many single-supply applications.
8.2 Typical Application
8.2.1 LMV3xxA Low-Side, Current Sensing Application
