The OPA344 and OPA345 series rail-to-rail CMOS
operational amplifiers are designed for precision, low-
power, 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.
