OPAx340 MicroAmplifier Operational Amplifiers

Texas Instruments OPAx340 MicroAmplifier™ Operational Amplifiers are a high-speed, rail-to-rail CMOS device optimized for low-voltage, single-supply operation. The TI OPAx340 op amps are ideal for driving sampling ADCs and is well-suited for general purpose and audio applications as well as providing I/V conversion at the output of DACs. The Texas Instruments OPAx340 op amps operate on a single supply as low as 2.5V with an input common-mode voltage range that extends 500mV below ground and 500mV above the positive supply.
