MN3005 instead of AD3208 in AD3208 delay

[sean k]

I'm drawing up the board for the AD3208 by Scott Swartz and have realised that because the 3205 and 3005 are basically the same thing and that I can use the 3205 instead of the 3208 then I should be able to use the 3005 given I'm etching my own board and can design around it.

I've done searches but have only found that the polarity between the 3005 and the 3205/3208 is different. Would this be an issue for me?

Taken that there is no issue, I hope , then would the pins count out around the 3005 as 1 - 8 and then on a 16 pin socket work out as 1=1, 2=2, 3=7, 4=8, 5=9, 6=10, 7=15, 8=16.(3205=3005)

Don't forget the differences with the clock circuitry (3102 vs. 3101).

...for a good example of the differences between the 3102/3205 vs. the 3101/3005 circuitry.
Hope this helps.

I got my pins wrong but given they number the same, 1-8, The only difference I can see is that V+ and V- are reversed between the 3208/3205 and the 3005. The 3101 and 3102 seem remarkably similar as well except I don't know precisely what or how the clocks work. The ins and outs, connections to clock and, apart from the V+ and V- swap, end for end I don't see that there would be a problem. It looks like I can power the 3005 from 9V as well instead of ...

Actually I'll forget about it and save the 3005's for a memory man. Just doing this has got me thinking about how the BBD stuff works so thats got to be a good thing. Thanks for your time Dave.
