Title: Identify an old (mid-1970s) 10-bit ADC
Post by: ballen on April 19, 2024, 12:45:36 pm

Can someone identify this ancient (circa 1975) ADC?  I'm pretty sure it is from Burr Brown but might also be Analog Devices.

Too many pins for an IC package of that era. It look more like a module - perhaps from Data Translation inc. I came across quite a few of them back in the day

Could it be a TRW part?

As I recall it was a module, one of those black potted things with lots of pins, both Burr Brown and Analog Devices made many components in that style in the 1970s and 80s.
Yes, it might have been TRW but I'm 90% sure that it was either Burr Brown or Analog Devices.

I'm trying again for a more reasonably-sized picture and the correct alignment.

[OK, that worked, also fixing it in the original post.]

maybe theses series ?

Burr Brown ADC80AG-10    but the pin count does not match

Dont forget Datel too

ANALOG DEVICE had some similarities ....  ????

i got it   almost   loll

as far my memory go    72 pins module where mostly Analog devices ???

cant recall Burr-Brown doing the same thing ?

maybe some catalogue is floating around ?

@op   where did you took this image ??

Hi ballen,
 
Analogic?

Pretty sure it's an ADC-10QU

I wonder about the strange counting order of the Bits with MSB on position 1 and LSB on 10(12)

OK I found it as what looks like Analog Devices ADC-10Z circa 1973.   https://archive.org/details/bitsavers_analogDevilogDevicesProductGuide_92605624/page/90/mode/2up (https://archive.org/details/bitsavers_analogDevilogDevicesProductGuide_92605624/page/90/mode/2up)

Floobydust, thank you very much, this is right, the ADC-10Z is a perfect match to my diagram!
