PRUDAQ

PRUDAQ is a fast ADC cape for BeagleBone Black and BeagleBone Green designed by Google Research.

Features:


 * Dual-channel simultaneously-sampled 10-bit ADC
 * Up to 20MSPS per channel (40MSPS total)
 * 0-2V input voltage range (DC coupled)
 * 4:1 analog switches in front of each channel provide a total of 8 single-ended analog inputs. (See here for differential input)
 * SMA jacks for direct access to the 2 ADC channels

Flexible clock options:


 * External input via SMA jack
 * Internal onboard 10MHz oscillator
 * Programmable clock from BeagleBone GPIO pins

It uses the BeagleBone PRUs to clock data into main memory for processing or storage.

The design is Free, or you can buy a pre-made board at GroupGets.
