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
common-mode 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 Con-
verters (ADC). They are also well suited for general
purpose and audio applicaitons and providing I/V con-
version 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.
