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

At 3.3v, the TS4973 is an Audio Power Amplifier capable of delivering 400mW of continuous RMS ouput power into a 8W bridged-tied loads with 1% THD+N, and 30mW( typ ) per channel of continuous average power into stereo 32W BTL loads with 0.5% THD+N from 20Hz to 20kHz. An external standby mode control reduces the supply current to less than 10nA. An internal over-temperature shutdown protection is provided.

The TS4973 has been designed for high quality audio applications such as mobile phones and to minimize the number of external components. It has two inputs which can be used to switch the gain between 6dB ( internal ) or a user's adjustable gain setting with one external resitance.
