The new DAC+ ADC Pro

We did it again. As we received a lot of requests for a DAC+ ADC with the clock design of the DAC+ Pro, here is is: the DAC+ ADC Pro.

There are some improvements compared to the DAC+ ADC:

  • Dual-domain clock design that provides a master clock independent from the Raspberry Pi
  • Fully configurable analogue front-end that allow a wide variety of input levels (from mic level to full 2Vrms) – no more jumpers, you can do the configuration in software using alsamixer
  • Microphone bias voltage allows to use electret microphones (needs to be enabled with jumpers)
  • Higher input bandwidth as we removed the anti-aliasing filter in the input path

Bases on these differences, we recommend the DAC+ ADC Pro for the following scenarios:

  • Everybody who likes the DAC+ Pro design
  • Audio recordings that require a higher bandwidth
  • Use of electret microphones
