General Description

The TS4990 is designed for demanding audio applications such as mobile phones to reduce the number of external components.

This audio power amplifier is capable of delivering 1.2 W of continuous RMS output power into an 8  load at 5 V.

An externally controlled standby mode reduces the supply current to less than 10 nA.
