Description

The TS4972 is an Audio Power Amplifier capable

of delivering 1.6W of continuous RMS ouput

power into a 4

Ω 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 TS4972 has been designed for high quality

audio applications such as mobile phones and to

minimize the number of external components.

The unity-gain stable amplifier can be configured

by external gain setting resistors.

Applications

■ Mobile phones (cellular / cordless)

■ PDAs

■ Laptop/notebook computers

■ Portable audio devices
