Description
At 3.3v, the TS4973 is an Audio Power Amplifier
capable of delivering 500mW of continuous RMS
output power into a 8
bridged-tied loads with 1%
THD+N, and 150mWof continuous average power
into 32
. 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 adjustable
gain setting with one external resistance.
Applications
