How to resolve the contention between 2 ADC0801!!!???
I would like using two ADC0801 in order to read 2 Vol electric signal ., 2 ADC interfaces with AT89c51 by using common input..If I use an ADC, no problem, but with 2 ADC ,ADC will not working!!!! Please help me!!!

Voltage dividers? How will that measure multiple voltage sources?
Where did you see the OP mention multiple voltage sources? I only see him mentioning "2 Vol electric signal" and "a single input". Now maybe I'm jumping to conclusions, but for now I'll assume he thought that if a single ADC's input range is 1 Volt, but the input is 2 Volts, he must use 2 ADCs.
I decided to decrypt "in order to read 2 Vol electric signal" into "in order to read two voltaic electric signals".
With unclear requests, it is always hard to know what is actually meant.
The only meaningful reason for two ADC would be an intention to read multiple signals. The alternative - running them off-phase for getting twice as many samples/second - is so complex that anyone who even get the idea would normally be expected to know how to resolve any contention problems.
