TS4994FC 1.2 W differential input/output audio power amplifier with selectable standby

The TS4994FC is an audio power amplifier capable of delivering 1W of continuous RMS output power into an 8Ω 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 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.
