Thanks to its differential inputs, it exhibits outstanding noise immunity. An external standby mode control reduces the supply current to less than 10nA. A STBY MODE pin allows the standby pin to be active HIGH or LOW (except in the MiniSO8 version). An internal thermal shutdown protection is also provided, making the device capable of sustaining shortcircuits. 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 has been designed for high quality audio applications such as mobile phones and requires few external components.
