TS4956 Datasheet | STMicroelectronics

Description The TS4956 is a plete audio system device with three dedicated outputs, one stereo headphone, one loudspeaker drive and one mono line for a hands-free set. The stereo headphone is capable of delivering more than 25 m W per channel of continuous average power into 16Ω single-ended loads with 0.3% THD+N from a 5 V power supply. The device functions are controlled via an I²C bus, which minimizes the number of external ponents needed. The overall gain and the different output modes of the TS4956 are controlled digitally by the control registers which are programmed via the I²C interface. It has also an internal thermal shutdown protection mechanism.
