Because component out is analog? Why would you offer an analog video output
and a digital audio output?
I've looked at these types of devices (ADC and DAC) for some time now.
Basically what I have found is that the DAC is FAR, FAR more common than the
ADC. Even though the two circuits are of similar complexity and size, for
some reason you can get a DAC for pennies but no one makes a SMALL, cheap
ADC. When I say cheap I mean less than $40-$50.
If you find one, let me know. I'm this close to laying one out and building
The above quoted device is a digital to analog converter. It won't convert
analog to S/PDIF. I don't think it will do what you're looking for.
PS I consider $80 for the above device fairly reasonable, even though the
actual circuitry can be had for about $30 on ebay, the above device has a
shiny case and an included power supply.
