Typical Application


The singleTP2431, dual TP2432, and quad TP2434 operational amplifiers combine excellent DC accuracy with Rail-to-Rail operation at the input and output. Since thecommon-mode voltage extends from VCC to VEE, the devices can operate fromeither a single supply (2.2V to 5.5V) or split supplies (±1.1V to ±2.75V). Eachop amp requires less than 190μA of supply current.

Even with thislow current, the op amps are capable of driving a 1kΩ load, and theinput-referred voltage noise is only 13nV/√Hz. In addition, these op amps candrive loads in excess of 2000pF.

The precision performance of theTP2431/TP2432/TP2434 combined with their wide input and output dynamic range,low-voltage, single-supply operation, and very low supply current, make them anideal choice for battery-operated equipment, industrial, and data acquisitionand control applications.

The TP2431 issingle channel version available in 8-pin SOP and 5-pin SOT23 packages. TheTP2432 is dual channel version available in 8-pin SOP and MSOP packages. TheTP2434 is quad channel version available in 14-pin SOP and TSSOP packages.
