DESCRIPTION
At 3.3v, the TS4973 is an Audio Power Amplifier
capable of delivering 400mW of continuous RMS
ouput power into a 8
bridged-tied loads with 1%
THD+N, and 30mW( typ ) per channel of continu-
ous average power into stereo 32
BTL loads with
0.5% THD+N from 20Hz to 20kHz. An external
standby mode control reduces the supply current
to less than 10nA. An internal over-temperature
shutdown protection is provided.
The TS4973 has been designed for high quality
audio applications such as mobile phones and to
minimize the number of external components. It
has two inputs which can be used to switch the
gain between 6dB ( internal ) or a user’s adjust-
able gain setting with one external resitance.
