SGM4807
DESCRIPTION
The SGM4807 is an audio click-pop eliminator which can operate from a 1.7V to 5V single power supply. It is designed for portable devices.
The SGM4807 provides a low-impedance grounding path during startup and shutdown by connecting to the output of the system amplifier. It allows -VCC to +VCC wide range audio signals passing with low distortion. Shunt mode can eliminate the click-pop noise.
The SGM4807 has two low-impedance analog switches. The opening and closing of the switches are controlled by mute events that include external power supply and under-voltage of VCC, power-up, power-down and high to low logical level change of MUTE pin. Opening switches during normal operation will not affect the output signal.
