    PMod AD4 (16 bits/1MSPS)

    Hello @Ana-Maria Balas Thank you for your quick reply. The Pmod AD4 would have been the best compromise for my application (R = resolution> = 14 bits and SR = sampling rate > = 100 kSPs). I need a resolution greater than 12 bits (14 bits, 16 bits, ...). I also need a sampling frequency of at least 100 kHz (100 kSP). The sampling rates of PMOD-AD1 and AD2 are ok, but their resolutions (12 bits )are lower than I want (>= 14 bits). The PMOD-AD5 has good resolution (24 bits), but its sampling rate is less than what I need (4.8 kHz <100 kHz). Do you have another ADC-Pmod that meets these requirements (R >= 14 bits and SR >= 100 kHz)? Thanks! Herve

    PMod AD4 (16 bits/1MSPS)

    Dear all, Has Digilent stopped manufacturing and selling the Pmod AD4 (16 bits and 1 MSPs)? I can not find it online. Thank you. B.R Herve
  3. Thank you guys for all your help and assistance. In the end, I think the best solution would be to design a custom DAC that meets my needs, even if it takes me away for a moment from my main goal. I also think that if Digilent ever came up with Pmod ADC/DACs with a sample rate greater than 2 MSPs, this could be of interest to many people. Thanks! H
  4. This is the absolute group delay and not the delay uncertainty. If it was the delay uncertainty, yes I could mitigate it by interpolating the samples. Thank you. H
  5. Hi xc6lx45, A conventional audio codec will be insufficient because I have to control the delay of my processed signal with a precision of at least 0.5 us (2 MHz). Which means that if my DAC has a sampling rate lower than 2 MSPs, I could not reach the 0.5 us required! Thanks! H
  6. Hello everyone, I am looking for an ADC and a DAC of at least 2 MSPs and a resolution greater than or equal to 12 bits. I do not want to use ADC or DAC with an FMC type interface (I do not have enough free pins on my FPGA card). A serial type interface (SPI) would be nice. Are there PMODs that have these characteristics? If not, can you recommend an ADC / DAC with these characteristics (> 2 MSPs and> 12 bit resolutions)? I have to process signals of frequency <= 10 kHz and send them to a DAC with a resolution of at least 12 bits and an acquisition speed of at least 2 MSPs. Thank you! Regards H
