Looking for BA6110 help

[ayayay!]

What are the pinouts for the 9pin SIP BA6110 that Steve sells?  (Are you out there today Steve?   )

The only datasheet I've found is for the 18pin and that's definitely not going to be like the 9pin as it has a built in buffer on one side. 

Go easy on me, I have used the search and spent the better part of yesterday trying to find it before asking.

Can't lay my hands on it at the moment, but it strikes me that if you got the schem for the Boss CS-2 yo'd have pretty much all the info you need.

[ayayay!]

You're barking up the right tree, but i know the CS-2 used a BA662 and the pinout isn't the same, therefore the question.   

[Mark Hammer]

bAH!!! You're right.

I was thinking of the Nobels CO-2, found here: http://www.nobels.com/en/index.htm

Sorry about that.

Ahh, thank you Mark!!!

* BA6110 to BA662 pin conversion
Pin 1 = Pin 3
Pin 2 = Pin 2
Pin 3 = Pin 4
Pin 4 = Pin 1
Pin 5 = Pin 5
Pin 6 = Pin 6
Pin 7 = Pin 7
Pin 8 = Pin 8
Pin 9 = Pin 9

Sorry to dig up this old one, but what do I do w/ pins 7 & 8?

maybe I'm wrong, but I thought that the BA6110 needs a stronger input than the BA662, so you need a little circuit before pin 1 to give it more input..and then I'm not sure the pin conversion is the right one..

[Dimitree]

ops..just checked the 6110 datasheet, and it seems like you did a fine conversion.. The error was on my documents..I had a bad conversion, can't remember where I got that..but they just switched pin 2 with pin 3..and that should not work at all..

then, for the input, maybe you need something like this:


I hope I'm correct on this..(this schematic comes from the same place where I got the bad pin conversion..)

about pin 7 and 8, as the datasheet says, it should be a buffer, so pin 7 is the input and pin 8 the output, pin 3 the bias

[ayayay!]

So if I weren't to use them, I could probably just leave them alone.  Where did you find a datasheet for the BA6110?  Granted I haven't looked in 6 months, but I couldn't find one anywhere.  Can you provide a link?

THANK YOU!

I got it on my hard disk    can't remember where I got it..
PM me you email adress and I'll send you!

Awesome!  Thanks Dimitree!

now we should figure out how and why this 6110 needs a stronger input than the BA662.. Do we have a datasheet for the 662? so how we know that? and then, why the mini-amplify circuit is always connected on the pin 1 of the 6110, that is in fact the control pin, not the input pin..

[Dimitree]

does anyone know why the BA6110 should need a stronger input? Who and why mentioned that? sorry but I can't see no reasons since there's no BA662 datasheet.. Could anyone explain?
really thanks
