  • Product introduction

The OPA344 and OPA345 series of rail-to-rail CMOS operational amplifiers are designed for high-precision, low-power, small form factor applications. The OPA344 is unity-gain stable, while OPA345 is greater than or equal to five optimizations with a gain-bandwidth product of 3MHz.

The OPA344 and OPA345 are optimized for operation on a single 2.5V supply and with an input common-mode voltage range, exceeding the material from 300mV to 5.5V. Quiescent current is only 250μA maximum.

Rail-to-rail inputs and outputs make driving sampling analog digital converters ideal. They are also well suited for general purpose and audio applications and offer I/V conversion in the output of D/A converters.
