Eight analog voltages as simple (fewest parts) as possible?

Using Arduino General Electronics

Thanks all.

I wish Microchip would have used a couple of extra pins on the device and allowed address setting the old fashioned way.

  1. seems VCC & GND are valid voltages so 7 equal resistors say 1K @ 3.3V should be possible.
  2. trimpot just seems so sloppy, else it would be a obvious choice and cheap too.
  3. SPI is great & fast but I2C makes it easy to add more slave devices e.g. relay / opto boards, RTCC & EEPROM without adding a CS or CE line for each peripheral. I am open to suggestions though...
