I gave up trying to get my Max1112 ADC working - I think the chip was screwed up anyway. I've replaced it when a TI0838N which had a pretty close pin arangement, but not 100% the same. Regardless, when I hooked it up, it too does the same thing. (Inputs from any channel 0-7 are all read and sent to the mCU regardless of what channel I *want* to read.)

Has anyone in here ever used this ADC with your 8051 micro before?
