Hello Everyone,

I would need some advice on what type of down converting analog to digital Converter (ADC) board and an digital to analog converter (DAC) board to use for my digital radiometer. Here are the specs for my ideal boards:

Analog to Digital Converter requirements:



Single Input

12-16 Bit Resolution Output

High Signal To Noise Ratio (SNR)

Low Power Requirement (with one power supply preferrably)

80+ megasamples/second throughput/sample rate

Overall the ADC needs to be ideal for IF sampling applications.


Digital to Analog Converter requirements:


Single Output

12-16 Bit Resolution Input

Remaining requirments are similar to the one of the ADC



Are there any ADCs and DACs out there that could fulfill the above stated requirements? I would appreciate any feedback! Thank You!

I would start at National Instruments:

I use ads7841, 12-bit 4-channel ADC interface to 8051 micros.

If you are interested, please see:
