This Audio Amplifier is exhibiting 0.1% distortion level (THD) from a 5V supply for a Pout = 250m W RMS. An external standby mode control reduces the supply current to less than 10n A. 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 ponents. The unity-gain stable amplifier can be configured by external gain setting resistors.
