We’re done with the initial design of our audio ADC module. Latest changes include the addition of a U.FL connector for the master clock, a very clean ground plane, and a properly sized cutout. I’m especially pleased with the ground plane, which includes much less traces than with our previous iteration, and does not include any signals, be they digital or analog. Instead, it is used exclusively for grounding and power. Also, some extra space has been added between vias and traces, ensuring better isolation.

Next step: the R-2R sign magnitude DAM module.
