DESCRIPTION

The OPA344 and OPA345 series rail-to-rail CMOS

operational amplifiers are designed for precision, low-

power, miniature applications. The OPA344 is unity

gain stable, while the OPA345 is optimized for gains

greater than or equal to five, and has a gain-bandwidth

product of 3MHz.

The OPA344 and OPA345 are 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

250 A (max).

Rail-to-rail input and output make them ideal for driving

sampling analog-to-digital converters. They are also well

suited for general purpose and audio applicaitons and

providing I/V conversion at the output of D/A converters.

Single, dual and quad versions have identical specs for

design flexibility.

A variety of packages are available. All are specified for

operation from –40ºC to 85ºC. A SPICE macromodel is

available for design analysis.
