The OPA340 rail-to-rail CMOS operational amplifier is optimized for low-voltage, single-supply operation. Rail-to-rail input/output and high-speed operation make it ideal for driving sampling analog-to-digital (A/D) converters. The OPA340 is also well-suited for general purpose and audio applications as well as providing current/voltage conversion at the output of digital-to-analog (D/A) converters.

The OPA340 operates on a single supply as low as 2.7 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. It offers excellent dynamic response (BW = 5.5 MHz, SR = 6 V/µs), yet quiescent current is only 750 µA.

The surface mount package options are SOIC-8 or SOT23-5. Both are specified from –55°C to 125°C. A SPICE macromodel is available for design analysis.
