The single TP2431, dual TP2432, and quad TP2434operational amplifiers combine excellent DC accuracywith Rail-to-Rail operation at the input and output. Sincethe common-mode voltage extends from VCC to VEE,the devices can operate from either 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 this low current, the op amps are capable ofdriving a 1kΩ load, and the input-referred voltage noiseis only 13nV/√Hz. In addition, these op amps can driveloads in excess of 2000pF.The precision performance of the TP2431/TP2432/TP2434 combined with their wide input and outputdynamic range, low-voltage, single-supply operation,and very low supply current, make them an ideal choicefor battery-operated equipment, industrial, and dataacquisition and control applications.The TP2431 is single channel version available in 8-pinSOP and 5-pin SOT23 packages. The TP2432 is dualchannel version available in 8-pin SOP and MSOPpackages. The TP2434 is quad channel versionavailable in 14-pin SOP and TSSOP packages.
