OPA343 series rail-to-rail CMOS operational amplifiersare designed for low cost, miniature applications.They are optimized for low voltage, single supplyoperation. Rail-to-rail input/output and high speedoperation make them ideal for driving sampling analog-to-digital converters. They are also well suited forgeneral purpose and audio applications as well asproviding I/V conversion at the output of D/A converters.Single, dual, and quad versions have identicalspecifications for design flexibility.The OPA343 series operates on a single supply as lowas 2.5V, and input common-mode voltage range extends500mV beyond the supply rails. Output voltage swingsto within 1mV of the supply rails with a 100kW load.They offer excellent dynamic response (BW = 5.5MHz,SR = 6V/ms), yet quiescent current is only 850mA. Dualand quad designs feature completely independent circuitryfor lowest crosstalk and freedom from interaction.The single (OPA343) packages are the tiny 5-leadSOT-23-5 surface mount and SO-8 surface mount.The dual (OPA2343) comes in the miniature MSOP-8 surface mount and SO-8 surface mount. The quad(OPA4343) packages are the space-saving SSOP-16surface mount, SO-14 surface mount, and TSSOP-14surface mount. All are specified from –40°C to +85°Cand operate from –55°C to +125°C. A SPICEmacromodel is available.
