Audio delta-sigma ADC
Maturity plannedTargets ASIC (CMOS) onlyDifficulty HardPriority 1
Switched-capacitor delta-sigma modulator with decimation filter for audio band capture at 16 to 24 bits.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
