Product Summary

The OPA4344UA is a rail-to-rail CMOS operational amplifier designed for precision, low- power, miniature applications. The OPA4344UA is unity gain stable. The OPA4344UA is optimized to operate on a single supply from 2.5V and up to 5.5V with an input common-mode voltage range that extends 300mV beyond the supplies. Quiescent current is only 250μA (max). The applications of the OPA4344UA include pcmcia cards, data acquisition, process control, audio processing, communications, active filters and test equipment.
