DESCRIPTION

The TS4872 is an Audio Power Amplifier capable

of delivering 1W of continuous RMS Ouput Power

into 8Ω load @ 5V.

This Audio Amplifier is exhibiting 0.1% distortion

level (THD) from a 5V supply for a Pout = 250mW

RMS. An external standby mode control reduces

the supply current to less than 10nA. An internal

shutdown protection is provided.

The TS4872 has been designed for high quality

audio applications such as mobile phones and to

minimize the number of external components.

TYPICAL APPLICATION SCHEMATIC

The unity-gain stable amplifier can be configured

by external gain setting resistors.
