DESCRIPTION

The OPA342 series rail-to-rail CMOS operational

amplifiers are designed for low-cost, low-power, miniature

applications. They are optimized to operate on

a single supply as low as 2.5V with an input commonmode

voltage range that extends 300mV beyond the

supplies.

Rail-to-rail input/output and high-speed operation make

them ideal for driving sampling Analog-to-Digital Converters

(ADC). They are also well suited for generalpurpose

and audio applications and providing I/V conversion

at the output of Digital-to-Analog Converters

(DAC). Single, dual, and quad versions have identical

specs for design flexibility.

The OPA342 series offers excellent dynamic response

with a quiescent current of only 250μA max. Dual and

quad designs feature completely independent circuitry

for lowest crosstalk and freedom from interaction.
