Fast sampler for your Amiga



It works!
MAX153MAXIM chip.
high speed, 8 bit ADC
660ns Conversion Time
1Msps Throughput
Low Power: 40mW (Operating mode), 5µW (Powerdown mode)
Single +5V or Dual +-5V Supplies


Where to get?
Best place is old GSM phone Motorola flare!
Just open it and take it!


Here it is Motorola Flare GSM phone without cover:


Locate this part in the phone:


and solder out this chip (MAX153):

Now you can place it to Amiga audio sampler. (By the way, here you can find 68332 CPU which is brother of 68020 placed in A1200 :))

Search in old PCB boards or buy new chip: 74F04 or any from 74x04 familly. It is very common chip. I suggest you to find some in SOP/SMD package if you want to place your Fast Amiga Sampler in cable holder. Also you need some discrete parts: 10 resistors ~30Ohm to 100Ohm, 2 pcs. ~3.3K, one trimmer ~10K. (These details are not critical, use any in 30% range :)) Also you need some capacitors: 1 pcs 4.7µF, 2 pcs. ~0.1µF and maybe one 10µF.
(In my project I used all SMD parts. Why? You don't need to drill that damn small holes in PCB. Also if you want to you use my PCB you need to get them all SMD. Where to get them? I used old 386 notebook :) some other junk and (Oh my god!!) my old bad A1200 :(). You can find this details in shop, but I think you need to buy atleast 100pcs...)
