DESCRIPTION

The TS4902 is an audio power amplifier designed

to provide the best price to power ratio while pre-

serving high audio quality.

Available in MiniSO8 & SO8 package, it is capable

of delivering up to 0.7W of continuous RMS ouput

power into an 8

Ω load @ 5V.

TS4902 is also exhibiting an outstanding 0.1%

distortion level (THD) from a 5V supply for a Pout

of 200mW RMS.

An externally controlled standby mode reduces

the supply current to less than 10nA. It also in-

cludes an internal thermal shutdown protection.

The unity-gain stable amplifier can be configured

by external gain setting resistors.

APPLICATIONS

s Mobile Phones (Cellular / Cordless)

s PDAs

s Portable Audio Devices
