help on LC7822N

[diyfmradio]

Hi
I am currently buliding my own home thearter amp
so for the audio input selection section I found
a ic LC7822N in a old Oknyo Amp I had lying around..

now my question is how do you togle the various internal
switches on this Ic

I would like to simulate this on my breadboard before
I start writting a program for the PIC wich I wish to use
to control the whole amplifier.

I have read through the datasheet but i still don't understand how to do this.



Your help will be greatly apreciated...
Thanks in Advance.

Here is the Datasheet

What part don't you understand ?

Thanks for your reply...

ok here I go...
1. on the CE I put a Logic Low
2. I have to clock through A0 A1 A2 A3
3. take CE to a logic High
4. Then Clock through SW1 SW2 SW3 SW4 SW5 SW6 SW7 SW8
5. take CE to a logic Low

I am not sure What A0 A1 A2 A3 are suppose to be
I see that they are dependent on the s pin.
can I just tie the S pin to gnd & just use 0011

Thanks Again...

The S pin gives you two different addresses for when you use two chips. With one chip you can, as you say, ground the S pin and use 0011 as the chip address.

Thanks again....

now I get it....

Thanks a million for your Help Greatly apreciated

now I can Go on & Build ....
