stj:
what's the fastest way to do 6bit A-D at TTL levels??
can i manage atleast 20M-samples?
jonroger:
A parallel output ADC such as the AD9280?
OM222O:
can I ask why you want 6 bit ad TTL levels? that's quite course ... about 0.1V which is not really useful for any analog circuit.
if you're trying to build a crude logic analyzer, your best bet is voltage compactors, not an ADC. if you desperately want an ADC however, fastest ADCs are the flash topology which is available in the low resolutions that you are asking (i.e: 6 bit).
stj:
i want to convert a digital(supposedly) 5v signal into 6bit digital so i can read the logic state in .1v resolution.

in short, i want to make a logic probe that does not just indicate "high" or "low" but attempts to judge the signal level to detect failing i.c. outputs.
OwO:
AD9200 is only $1 and gets you 10 bits @ 20MSPS.
