appropriate ADC evaluation board

I am designing a single bit sigma delta ADC. My BW is 50mHz to 250Hz. Sampling frequency is 32kHz or 64kHz. To get a hands-on on testing the ADC, I am looking for an evaluation board with a similar ADC. Can u suggest me a suitable evaluation board for the same ? It would be good if I can view the output both at the 1-bit internal quantizer and the output of the decimation filter.

  • Hi Jovialjha,

         Below is the short list of Sigma delta ADC that possibly fit to your requirement.

         ADI Sigma-Delta ADC portfolio range from 8bit to 24 bit resolution. And these parts are available with their evaluation board and software, you can visit ADI website Analog Devices | Mixed-signal and digital signal processing ICs  for details. In case you wanted search other products base from your specification, you use parametric search .Please refer to link Selection Table for Precision below.

    These ADCs are already packaged and access to the output quantizer might not be possible. There is the Dout, pin which outputs the conversion results.
