I was wondering if it was possible to use two GP2D12's with one adc0831? Or would each require it's own adc? Thanx again _Duane

Hello,
··· You could use a multi-channel ADC.· That would allow more than one sensor per ADC chip.· But one ADC0831 can't do it without an analog multiplexer or switch.

Hello,
·· Here's a 2-channel ADC which could work, and has more resolution than the ADC0831...

·· Of course there are more flavors of the ADC0831, I believe the ADC0834?· ADC0838?· Multi-Channel version of 4 and 8 channels, if memory serves.
