No Zipper, No Pop! How ADC Hybrid Gain Control Can Enable Smooth, Pop-Free Microphone Preamp Gain Changes

This article explains the new hybrid gain control (HGC) feature of Cirrus Logic’s latest CS530xP family of Pro Audio ADCs and how these can eliminate noise problems when changing gain on digitally controlled mic preamps. This solution enables fine-resolution mic preamp gain control, with the feel of a traditional potentiometer but without audible pops or zipper noise by integrating control into the ADC, together with zero-cross detection and precisely synchronized digital gain control.
