The OPA2277UA precision amplifier manufactured by Texas Instruments is a dual hi-precision amplifier designed for high-precision audio applications and high-performance sound systems. It is ideal for use as a low-noise, low-distortion audio amplifier in applications such as audio preamps, mixers, effects processors, and instrument amplifiers. The device features two low-noise, low-distortion wide bandwidth amplifiers with a very low output offset voltage, low output noise and high input impedance. It also features variable gain, precision temperature compensation, low quiescent current, and a single-supply operating range. Additionally, it has superior performance over the extended temperature range of -40°C to +85°C.
