Description
The TS4956 is a complete 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 mW per
channel of continuous average power into 16
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 components 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.
Applications
■
Mobile phones (cellular / cordless)
■
PDAs
■
Laptop / notebook computers
■
Portable audio devices
