I am wondering if I could use a DAC+ ADC Pro card for a low-cost measurement system? The datasheet (https://www.hifiberry.com/docs/data-sheets/datasheet-dac-adc-pro/) lacks a lot of real data, so one question is, for decent measurements it would be advisable with a low output impedance (preferably less than 0.2 ohm) - what is the output impedance? Are there any coupling capacitors or is it capable of providing DC output? What is the input impedance of the analog input? Are left and right channel synchronized, or should I expect 1/2 or 1/1 sample offset between channels?
