Audio Click/Pop Eliminator Saves Space

With an eye on portable multimedia devices, the MAX9892 shunt-mode, audio click-and-pop eliminator delivers 35 dB of click-and-pop suppression. Available in UCSP and microDFN packages, it requires one 0.1-?F capacitor to complete the circuit. The device eliminates noise on power and shutdown cycles by connecting to the output of the existing amplifier and providing a low impedance path to ground during power on/off. Two low-impedance analog switches stay open and do not affect the outcome signal during normal operation. These switches turn on during startup and shutdown to shunt the clicks and pops to ground. Additionally, the MAX9892 operates from a 1.7V to 3.6V supply and consumes 1 ?A of supply current. Prices start at $0.38 each/1,000 and an evaluation kit is available.
