Due to its differential inputs, The TS4994 is designed for high quality audio it exhibits outstanding noise immunity. applications such as mobile phones and requires few external components. An external standby mode control reduces the supply current to less than 10nA. An STBY MODE pin allows the standby to be active HIGH Applications or LOW (except in the MiniSO-8 version). An Mobile phones (cellular / cordless) internal thermal shutdown protection is also provided, making the device capable of sustaining Laptop / notebook computers short-circuits.
