Texas Instruments OPA4340UA

The OPA340 series rail-to-rail CMOS operational amplifiers are optimized for low-voltage, single-supply operation. Rail-to-rail input and output and high-speed operation make them ideal for driving sampling analog-to-digital (A/D) converters. They are also well-suited for general purpose and audio applications as well as providing I/V conversion at the output of digital-to-analog (D/A) converters. Single, dual, and quad versions have identical specifications for design flexibility.

The OPA340 series operate on a single supply as low as 2.5 V with an input common-mode voltage range that extends 500 mV below ground and 500 mV above the positive supply. Output voltage swing is to within 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 current is only 750 A. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction.

The single (OPA340) packages are the tiny 5-pin SOT-23 surface mount, 8-pin SOIC surface mount, and 8-pin DIP. The dual (OPA2340) comes in the miniature 8-pin VSSOP surface mount, 8-pin SOIC surface mount, and 8-pin PDIP packages. The quad (OPA4340) packages are the space-saving 16-pin SSOP surface mount and 14-pin SOIC surface mount. All are specified from –40°C to 85°C and operate from –55°C to 125°C. A SPICE macromodel is available for design analysis.
