TP2432-SR

The single TP2431, dual TP2432, and quad TP2434 operational amplifiers combine excellent DC accuracy with Rail-to-Rail operation at the input and output. Since the 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). Each op amp requires less than 190μA of supply current. Even with this low current, the op amps are capable of driving a 1kΩ load, and the input-referred voltage noise is only 13nV/√Hz. In addition, these op amps can drive loads in excess of 2000pF. The precision performance of the TP2431/TP2432/ TP2434 combined with their wide input and output dynamic range, low-voltage, single-supply operation, and very low supply current, make them an ideal choice for battery-operated equipment, industrial, and data acquisition and control applications. The TP2431 is single channel version available in 8-pin SOP and 5-pin SOT23 packages. The TP2432 is dual channel version available in 8-pin SOP and MSOP packages. The TP2434 is quad channel version available in 14-pin SOP and TSSOP packages.
