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 250

A 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 opera-

tion 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 degrada-

tion 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.
