TDA1308AUK,027

Overview

The TDA1308AUK,027 is a Class-AB stereo headphone driver fabricated in a 1 μm CMOS process. It operates on a single supply voltage of 3.0 V to 7.0 V or dual supplies of ±1.5 V to ±3.5 V. The device delivers up to 80 mW output power with THD+N below 0.1%. Key electrical parameters include a typical signal-to-noise ratio of 110 dB, a slew rate of 5 V/μs, and a supply current of 3 mA at no load. It functions within an ambient temperature range of -40°C to +85°C.
