help on finding datasheet

bowdown · 13th October 2004, 01:42 AM

Hi everyone just wandering if anyone has or knows where to get a datasheet for an NJM2068SD, The original part im repalcing is an NJM2068LD made by JRC.I have searched for a few days now and can not seem to find a datasheet. I ordered this part thinking it would be the same but instead of 8 pins its got 9 pins, I was hoping to find the datasheet and see if there is any way i can use this part instead of the original as i cant get hold of them and i need 8.. Please help.

Regards

Bowdown

Dear fellow Aussie, how's things out West? You may get some joy at http://www/icxinyi.com/EN/zlsearch.php I just put the part number plus the word data in "google" and got a couple of pages (some of which were in Eng.) This one looked promising but they will want money for the info' I suspect. If you put your original part no. in "Google" it seems to throw up quite a few sites. I think one said it was a dual op amp' is that right? Good luck.

Pinout for NJM2068SD:

1: V+
2: A Out
3: A -In
4: A +In
5: V-
6: B +In
7: B -In
8: B Out
9: V-

That pin out is not correct.

The power supply pins are wrong, pin 9 is also V+

The 9 pin sips are made so you cannot put them in backwards.

I guess you are correct, djk
Thanks for pointing that out

We can blame the Grundig engineers here.
