Does anyone know of a simple very basic functionality A/D and D/A converter I can use I only want to digitize voice at no more than 4khz. I have never used an A/d before so it must be quite simple to use-
I don't not want to use a microprocessor of any kind...

Any idea's

Thanks

You need to tell us more about what you are trying to do. A/D and D/A seems like a waste of time.

a/d

I want to use it for an optical intercom via infra red- I assume that if i send Bits to the TX (i.e. digital) then using the reciever as an opto schmitt trigger I will get a high quality signal. Thats my thinking. Im not sure if it's right though.

You will want to use Manchester coding in order to recover the data at the receiving end.

By the time you filter the important high frequencies out of your high quality signal to feed to the AD then filter the square-waves out of the DA, it will sound awful!

Could consider PWM or FM, both easier than AD-DA
