Click-Pop Suppressors

Analog Devices provides integrated audio click-and-pop suppressors for devices, such as codecs that have integrated headphone amplifiers but lack a clickless and/or popless startup or shutdown. Our integrated click-pop suppression device control the ramping of the DC bias voltage on the output-coupling capacitors and the application of the audio signal to ensure that no audible transients are present at the headphones. Our audio click-and-pop suppressors help eliminate clicks and pops for a variety of applications such as portable multimedia devices, headphones, and audio line outputs.
