Audio delta-sigma DAC
Maturity plannedTargets ASIC (CMOS) onlyDifficulty HardPriority 1
Interpolating digital delta-sigma modulator with multi-bit switched-capacitor or current DAC and reconstruction filter for audio playback.
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.
