DESCRIPTION

The OPA344 and OPA345 series rail-to-rail CMOS
operational amplifiers are designed for precision, low­power, miniature applications. The OPA344 is unity
gain stable, while the OPA345 is optimized for gains
greater than or equal to five, and has a gain-bandwidth
product of 3MHz.

The OPA344 and OPA345 are optimized to operate on
a single supply from 2.5V and up to 5.5V with an input
common-mode voltage range that extends 300mV
beyond the supplies. Quiescent current is only
250µA (max).

Rail-to-rail input and output make them ideal for driving
sampling analog-to-digital converters. They are also well
suited for general purpose and audio applicaitons and
providing I/V conversion at the output of D/A converters.
Single, dual and quad versions have identical specs for
design flexibility.

A variety of packages are available. All are specified for
operation from –40ºC to 85ºC. A SPICE macromodel is
available for design analysis.

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,

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.
