HELP on Xaoc Devices Drezno II

Loersatz

Hi :)
I am interested in this module but would like to know if there is an alternative as the LEFT side of this module (analog-to-digital-converter) is the one I am interested in.
Is there such a "reduced version" of this module? Whether from XAOC or another brand?
Thanks for any help or hint on the subject,
L

There are analog implementations of ADCs in Eurorack in the form of R-2R resistance ladders. Equation Group by Wildfire Laboratories is one example.

Thanks for the info.
Will have a look at it.

There are a couple of Beers modules that might interest you:

Thank you Enrico :)
Will also have a look... That 8 bit stuff is a new concept for me but I have seen/listened to some pretty nice stuff done with various modules and thathas caught my attention. Had no idea about this brand though.
Best,
L

R-2R ladder is a simplified implementation of a DAC, not an ADC. So this could be a substitute of the right side of Drezno, not the left side.

You're right. I suppose you'd need a reference voltage and a comparator per output to make it an ADC.

Thanks to both for following up :) Much appreciated.

Much more than that. Analog to digital conversion is complex and is usually handled by a dedicated chip. For discrete implementation you would need either 2^n-1 comparators where n is the number of bits (eg 255 comparators for 8 bits) and a string of 2^n resistors plus a complex network of data encoding gates, OR a complicated state machine that performs a quick series of measurements with a set of thresholds per each input sample.
