The TS4890 is an audio power amplifier, which can deliver 1 W of continuous RMS output power into 8 W load @ 5 V.

This audio amplifier shows 0.1% distortion level (THD) from a 5 V supply for a Pout = 250 mW RMS. An external standby mode control reduces the supply current to less than 10 nA. An internal thermal shutdown protection is also provided.

The TS4890 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.
