Description
The TS4975 is a stereo audio headphone driver
capable of delivering up to 102mW per channel of
continuous average power into a 16
single-
ended 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.
A phantom ground configuration allows one to
avoid using bulky capacitors on the outputs of the
headphone amplifiers.
The TS4975 is packaged into a 1.8mm X 2.3mm
Flip Chip package, ideally suited for space-
conscious portable applications.
It has also an internal thermal shutdown
protection mechanism.
