Note: Current stock is all PCBs left and I have no plans to make more due to very slow and painful assembly (there are 150 components). There may be simpler version one day in the future but nothing planned yet.
Detailed information and measurement results are available.
Fully tested board comes as in the photo; with all components soldered and no connectors. Audio connectors can be wired out, or optional XLRs can be soldered at the edge of the board (not fully fitting PCB due to lack of space).
Full measurement results, schematics, and more detailed information are available at nihtila.com and video below.
Signal level is 3.3 V.
Supports a range of clocks but 24.576 MHz is recommended.
This ADC has I2S output and you should be familiar with the format prior to buying.
I2S consists of:
The board can be configured as I2S Master or Slave. A wide range of sample rates is supported up to 768 kHz.
When used as Slave and in Auto clock mode, no clock configuration is needed. When Master, clocks are set using jumper links.
Following supply voltages and currents are required:
±15 VA are used for opamps so they are not very strict. I wouldn’t go higher due to excess power consumption but it can be lower. 5 V cannot be higher than 5.5 V.
The board gets quite warm in normal operation.
There are jumper links to set various settings such as clocking and digital filters. Please see the factsheet for more information.
If still unclear, please drop me a message.
Mono or Stereo
Default configuration for the board is stereo, meaning two balanced analog inputs and conventional stereo I2S output.
Another option is mono where most of the input circuit is doubled where we gain 3dB in dynamic range and SNR. In this case there is a single balanced stereo input. Output is still 2-channel I2S but both channels have the same data. Obviously for stereo application you need two mono boards.
I2S to S/PDIF
I have another product for sale which converts I2S to S/PDIF, and it is compatible with this ADC. It also has a special feature of creating one stereo S/PDIF from two of these ADCs in mono mode.
Note that at the moment stereo boards are ready to be shipped immediately but mono boards take a few more days.
If you need higher amount than in stock please contact me.
