1. All voltages values are measured with respect to the ground pin.
2. The magnitude of input signal must never exceed VCC + 0.3V / GND - 0.3V
3. Device is protected in case of over temperature by a thermal shutdown active @ 150°C.
4. Exceeding the power derating curves during a long period, will cause abnormal operation.


Description

The TS4902 is an audio power amplifier designed to provide the best price to power ratio while preserving high audio quality.

Available in MiniSO8 & SO8 package, it is capable of delivering up to 0.7W of continuous RMS ouput power into an 8W 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 includes an internal thermal shutdown protection.

The unity-gain stable amplifier of the TS4902 can be configured by external gain setting resistors.
