OPA2344UA/2K5 DESCRIPTION

The OPA344 and OPA345 series rail-to-rail CMOSoperational 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 equalto five, and has a gain-bandwidth product of 3MHz.The OPA344 and OPA345 are optimized to operate on asingle supply from 2.5V and up to 5.5V with an inputcommon-mode voltage range that extends 300mVbeyondis onlythe supplies. Quiescent current250µA (max).Rail-to-rail input and output make them ideal for drivingsampling analog-to-digital converters. They are also well suitedfor general purpose and audio applications and providing I/Vconversion at the output of D/A converters. Single, dual andquad versions have identical specs for design flexibility.A variety of packages are available. All are specified foroperation from –40ºC to 85ºC. A SPICE macromodel fordesign analysis is available for download from www.ti.com.
