   — S/N = 80 dB, THD + N = 0.025% (typical, A compensation filter used)
   — Digital output: MSB first, forward packed, bit clock rates of 32, 48, and 64 Fs
   — External integrator used.
• D/A Converter Block
   — 16× oversampling quadratic noise shaper + PWM
   — 16-bits resolution
   — D/A Converters for two channels built in (synchronized output)
   — S/N = 85 dB, THD + N = 0.03% (typical, A compensation filter used)
   — Digital input: MSB first, backward packed, bit clock rates of 32, 48, and 64 Fs

   Notes: Only the A/D Converters operate when 384 Fs is selected as the master clock. The D/A Converters do not operate in this mode. Since the analog I/F and analog power supply pins are more susceptible to damage from static electricity than the other pins, extra care is required.
