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 Ω load at 5 V.


An externally controlled standby mode reduces the supply current to less than 10 nA. It also includes an internal thermal shutdown protection.


The unity-gain stable amplifier can be configured by external gain setting resistors.
