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 TLV904x family of low-power, rail-to-rail input and output operational amplifiers is specifically designed for

portable applications. The devices operate from 1.2 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 resitive loads greater

than 2-kΩ connected to any point between V+ and V–. The input common-mode voltage range includes both

rails and allows the TLV904x series to be used in many single-supply or dual supply configurations.
