The TLV900x series of low-power, rail-to-rail input and output operational amplifiers are designed for portable applications. These devices operate from 1.8V to 5.5V, are unity-gain stable, and are suitable for a wide range of general-purpose applications. The Class AB output stage is capable of driving loads less than or equal to 10kΩ connected to any point between V+ and V-. The input common-mode voltage range includes both supply rails, supporting the use of TLV900x devices in many single-supply applications.
