STMicroelectronics TS4975

The TS4975 is a stereo audio headphone driver capable of delivering up to 102mW per channel of continuous average power into a 16Ω singleended load with 1% THD+N from a 5V power supply. The overall gain of these headphone drivers is controlled digitally by volume control registers programmed via the I2C interface, minimizing the number of external components needed. This device can also easily be driven by an MCU to select the output modes, through the I2C bus interface.
