Description
The TS4994 is an audio power amplifier capable
of delivering 1W of continuous RMS output power
into an 8
load @ 5V. Thanks to its differential
inputs, it exhibits outstanding noise immunity.
An external standby mode control reduces the
supply current to less than 10nA. A STBY MODE
pin allows the standby pin to be active HIGH or
LOW (except in the MiniSO8 version). An internal
thermal shutdown protection is also provided,
making the device capable of sustaining short-
circuits.
The device is equipped with Common Mode
Feedback circuitry allowing outputs to be always
biased at Vcc/2 regardless of the input common
mode voltage.
The TS4994 has been designed for high quality
audio applications such as mobile phones and
requires few external components.
