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.
