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
250mA (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.
