Hello,
Here i am facing problem of signal cross talk between ADC128 consecutive channels,
so when i apply some high Voltage say 5 V on 1st channel of ADC and 0 V on 2nd channel of ADC and rest of the ADC Channels are also on 0 V , and i send instruction to read all 8 channel of ADC so i get result as,
1st channel = 4095
2nd channel = 18 #problem is here i should get 0 digital reading here because i applied 0 V on this channel
3rd channel = 0
4th channel = 0 and so on all 0 digital reading till 8 channel,
and this problem is constantly repeating and also when i apply high voltage on other channel say 3rd channel and all other channels are grounded so i see the high voltage effect of 3rd channel on 4th channel,
So basically when i apply high voltage on a channel of ADC it is effecting the Next channel so i need a solution on how to avoid or rectify this problem ?
