Shunt Mode Audio Click-Pop Eliminator

GENERAL DESCRIPTION

FEATURES

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.

• Supply Voltage Range: 1.7V to 5V

• Pop/Click Reduction Circuitry

• Supply Current: 1.5μA (TYP)

• 600kΩ Pull-Low Resistor at

MUTE

The SGM4807 provides a low-impedance grounding

path during startup and shutdown by connecting to the

output of the system amplifier. It allows -V_CCto +V_CC

wide range audio signals passing with low distortion.

Shunt mode can eliminate the click-pop noise.

• -40℃ to +85℃ Operating Temperature Range

• Available in Green TDFN-2×2-8L, MSOP-8 and

WLCSP-1.57×0.80-8B Packages

APPLICATIONS

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 V_CC, power-up,

power-down and high to low logical level change of

pin. Opening switches during normal operation

MUTE

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℃.
