The CXAR41208 is an audio Click-Pop eliminator for portable multimedia devices. Operating from a 1.7V to 5V power supply, the CXAR41208 connects to the output of the existing system amplifier and provides a low-impedance path to ground during startup and shutdown. The inputs INL and INR accept voltage swings from +V_CC to -V_CC. The power-up and power-down transients are shunted to ground to prevent Clicks-Pops from becoming audible.

The CXAR41208 features two low-impedance analog switches controlled by mute events that open and close the switches. The mute events include under-voltage of V_CC and external power supply, power-up, power-down and high to low logical level change of nMUTE pin. The switches are open during normal operation and have no impact on the output signal. During startup and shutdown of the amplifier, the CXAR41208 can be activated to short the outputs to ground and prevent Clicks-Pops from pulling current through the line-outs.UFg嘉泰姆

The CXAR41208 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℃.UFg嘉泰姆
