Overview

The MAX9892ERT+ is an audio click-and-pop eliminator for portable multimedia devices. Operating from a 1.7V to 3.6V supply, the MAX9892ERT+ 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 VDD to 5.5V below VDD. See the Setting the Supply Voltage section in the full data sheet for more information. The power-up and power-down transients are shunted to ground to prevent clicks and pops from becoming audible. The MAX9892ERT+ features two low-impedance analog switches controlled by active-low MUTE that opens and closes the switches. The switches are open during normal operation and have no impact on the output signal. During startup and shutdown of the amplifier, the MAX9892ERT+ can be activated to short the outputs to ground and prevent clicks and pops from pulling current through the headphones. The MAX9892ERT+ is available in 6-bump UCSP (1mm x 1.52mm x 0.6mm) and 6-pin μDFN (2mm x 2mm x 0.75mm) packages. The MAX9892ERT+ is specified over the -40°C to +85°C temperature range.
