Description：

The OPA340 series rail-to-rail CMOS operationalamplifiers are optimized for low-voltage, single-supplyoperation. Rail-to-rail input and output and highspeed operation make them ideal for driving samplinganalog-to-digital (A/D) converters. They are also wellsuited for general purpose and audio applications aswell as providing I/V conversion at the output ofdigital-to-analog (D/A) converters. Single, dual, andquad versions have identical specifications for designflexibility.

The OPA340 series operate on a single supply as lowas 2.5 V with an input common-mode voltage rangethat extends 500 mV below ground and 500 mVabove the positive supply. Output voltage swing is towithin 1 mV of the supply rails with a 100-kΩ load.These devices offer excellent dynamic response(BW = 5.5 MHz, SR = 6 V/µs), yet quiescent currentis only 750 A. Dual and quad designs featurecompletely independent circuitry for lowest crosstalkand freedom from interaction.The single (OPA340) packages are the tiny 5-pinSOT-23 surface mount, 8-pin SOIC surface mount,and 8-pin DIP. The dual (OPA2340) comes in theminiature 8-pin VSSOP surface mount, 8-pin SOICsurface mount, and 8-pin PDIP packages. The quad(OPA4340) packages are the space-saving 16-pinSSOP surface mount and 14-pin SOIC surfacemount. All are specified from –40°C to 85°C andoperate from –55°C to 125°C. A SPICE macromodelis available for design analysis.
