Single rail-to-rail operational amplifier, OPA340NA/3K, Texas Instruments

The OPA340 is a rail-to-rail CMOS operational amplifier optimized for low-voltage, single-supply operation. Its rail-to-rail input and output, along with high-speed performance, make it ideal for driving sampling analog-to-digital (A/D) converters. It is also well-suited for general-purpose and audio applications, as well as for providing I/V conversion at the output of digital-to-analog (D/A) converters. The OPA340 operates 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. The output voltage swing reaches to within 1 mV of the supply rails with a 100-kΩ load. It offers excellent dynamic response (bandwidth = 5.5 MHz, slew rate = 6 V/µs), while consuming only 750 µA of quiescent current. The OPA340 features internal circuitry designed to minimize crosstalk and ensure freedom from interaction.
