ADAU1966 with Passive Filters (DAC-ADAU1966)

A hardware or SPI controlled 16 channel DAC based on the ADAU1966 from Analog Devices with TDM data inputs. With up to 118dB SNR and -98dB THD the ADAU1966 is a high performance audio DAC. It features 16 differential audio outputs and with it's relatively low cost offers a huge amount of performance for the money. The option of hardware control allows the board to operate independently  of other hardware. Control over SPI allows use of the DSP board or a separate microcontroller for more control.
