  • De-emphasis filter: Supports fs = 32 kHz, 44.1 kHz, or 48 kHz.
  • Soft mute.
  • Noise shaper.
  • Supports double-rate sampling.
  • D/A converter.
  • Dynamic level-shifting 18-bit digital-to-analog converter.
  • On-chip 2-channel D/A converter (with corresponding output).
  • On-chip output op-amp.
