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 Converters (ADC). They are also well suited for general
purpose and audio applicaitons 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.

NOTES: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only. Functional operation of the device at these conditions, or beyond the specified operating
conditions, is not implied. (2) Input terminals are diode-clamped to the power
supply rails. Input signals that can swing more than 0.5V beyond the supply
rails should be current-limited to 10mA or less. (3) Short-circuit to ground,
one amplifier per package.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
