About THDB-ADA and other AD/DA Daughter cards

Hi Dav,

Thanks for your response.

Actually, I want to sample analog signals with the frequency of 5 Hz and up to 100 kiloHz. Moreover, in my case, the analog signal consists of the pulses with ultrashort pulse durations (e.g. ~ 30-40 ns). For this reason, I need an high speed AD/DA daughtercard (or a FPGA board with built-in AD/DA operation) to sample each pulse properly. Therefore, AD/DA cards with very high sampling rates are required and I believe that Arduino based solutions would be insufficient.

I was thinking to use THDB-ADA with Cyclone III FPGA Starter Kit (or similar FPGA development boards in the same price range).

In addition, after some research, I found another FPGA development kit: ADC-SoC

It has a built-in ADC option up to 150 MSPS. However, I have checked the User's Manual and couldn't find any information about the DC signal support.

By the way, I am open to alternative design configurations to sample such an analog signal with ultra narrow nanosecond pulses.

Thanks,
