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. q GAIN-BANDWIDTH OPA344: 1MHz, G ≥ 1 OPA345: 3MHz, G ≥ 5 q SLEW RATE OPA344: 0.8V/µs OPA345: 2V/µs q THD + NOISE: 0.006% APPLICATIONS q q q q q q...
