DS1881 – a clickless dual digital attenuator

Audio engineers and hobbyists have long battled an annoying problem with digital potentiometers: an audible click or pop when changing volume levels. According to Adafruit Blog, Analog Devices' DS1881 integrated circuit addresses this frustration. The chip is a clickless dual digital attenuator with I-two-C interface and logarithmic response, making it ideal for microcontroller-controlled audio. For embedded systems developers working on audio projects, this could eliminate a persistent design nuisance.
