1.All voltage values are measured with respect to the ground pin.
2.The magnitude of the input signal must never exceed VCC + 0.3V / GND - 0.3V.
3.The device is protected by a thermal shutdown active at 150


Description

The TS4994 is an audio power amplifier capable of delivering 1W of continuous RMS output power into an 8 load @ 5V. Due to its differential inputs, it exhibits outstanding noise immunity.An external standby mode control reduces the supply current to less than 10nA. An STBY MODE pin allows the standby to be active HIGH or LOW. An internal thermal shutdown protection is also provided, making the device capable of sustaining short-circuits.

The device TS4994 is equipped with common mode feedback circuitry allowing outputs to be always biased at VCC/2 regardless of the input common mode voltage.

The TS4994 is designed for high quality audio applications such as mobile phones and requires few external components.
