Description

The TS4990 has been designed for demanding audio applications such as mobile phones and to minimize the number of external components.

This Audio Power Amplifier TS4990 is capable of delivering 1W of continuous RMS Ouput Power into an 8W load @ 5V.

An externally controlled standby mode control reduces the supply current to less than 10nA. TS4990 also includes an internal thermal shutdown protection.

The unity-gain stable amplifier TS4990 can be configured by external gain setting resistors.
