Hi Fausto, The sensor already provides a *digital* PDM output. I want to input it into the MCC Digital I/O channel rather than Analog Input. Would you *not* recommend that? My understanding is that the 1MHz you are referring to is the max rate of the card AO channel itself. Is there another channel (e.g., trigger) that can be used for the clock at higher frequencies? Maybe we need to look at another MCC card instead? Please advise. I would expect 4-8 of these sensors connected to 1 card. I still need at least 2 AOs to generate analog waveforms ~ 100 to 20,000 Hz. Thank you, Sepehr

Hi Fausto, Thank you for your prompt response. Yes, I would power from the card itself or an independent power supply. My thoughts were to input the PDM signal from the sensors into the digital input channels on the card (multiple sensors, multiple DIs) and decode the incoming signal from there. Would that work, or is there more that needs to be done? The second question is regarding sensor timing input. The sensor requires a clock input (F=1.2, 1.536,2.4, or/and 3.072MHz) - I presume I could use one DO/AO from the card or a trigger channel to give a clock signal. Am I missing something, or should the card be able to handle the above just fine? Regards, Sepehr

Greetings. I am starting a new project and need to connect a PDM sensor found here: https://www.digikey.com/en/products/detail/knowles/V2S200D/18670159 to a DAQ software such as MATLAB using your MCC USB-1208HS-4AO: High-Speed USB DAQ Device found here: https://digilent.com/shop/mcc-usb-1208hs-4ao-high-speed-usb-daq-device/ I have very limited knowledge and experience in electronics. Please advise.
