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.
The SGM4807 can be activated during startup and shutdown of the amplifier to short-circuit the output to the ground and reduce clicks-pops.
The SGM4807 is available in Green TDFN-2×2-8L, MSOP-8 and WLCSP-1.57×0.80-8B packages. It operates over an ambient temperature range of -40℃ to +85℃.
