DESCRIPTION
The TS4990 has been designed for demanding
audio applications such as mobile phones and to
minimize the number of external components.
This Audio Power Amplifier is capable of deliver-
ing 1W of continuous RMS Ouput Power into an
8
load @ 5V.
An externally controlled standby mode control re-
duces the supply current to less than 10nA. It also
includes an internal thermal shutdown protection.
The unity-gain stable amplifier can be configured
by external gain setting resistors.
