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, involves abnormal operating condition.


Description

The TS4972 is an Audio Power Amplifier capable of delivering 1.6W of continuous RMS ouput power into a 4W load @ 5V.

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

The TS4972 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.
