SAD1024

P

Pierre-François

No problem, it's a pleasure...

Sorry for the guys who wanted to do business, but I'll not sell few chips I
kept for 30 years just in case in my "tiroir"...

"It's so SAD a situation"...and yet the song was explicit: "take a SAD 1024,
and make it better"

I apologize. I didn't see that.

No worries. I didn't catch the next-page link the first time
either.

Just so you know, some BBD chips are still in production.
Shanghai Belling have cloned some of Panasonic MN3xxx devices.
They are distributed by an outfit named COOLAUDIO. All caps, no
space, that wouldn't be hip enough.

http://www.coolaudio.com/

V3207 = MN3207 (1024 stages)
V3208 = MN3208 (2048 stages)
V3205 = MN3205 (4096 stages)
V3102 = MN3102 (clock driver)

No idea whether they can substitute for the SAD1024.

Hello,

the good thing with SAD1024 is the clock can grow up to 1 MHz. This is
usefull for me 'cause I wish a 1 ms delay, no more.

regards

That reminds me of Silicon Chip's LP Doctor kit:

http://www.siliconchip.com.au/cms/A_101231/article.html

It uses an old (obsolete) Mitsubishi M65830P digital delay with
built-in A/D and D/A converters and 16Kbit RAM:
