I am using ADS1112 in a proven design. I have one sample of ADS1112 that goes into a failure mode where all channels read as zero with respect to AIN3. Power cycling resolves the failure. It happened twice. I have swapped the part for a new one, leaving everything else the same. The two times I've seen this failure mode occurred within 24 hours of use.
If it occurs again with a fresh part, I'll know there's something else wrong causing the ADS1112 to latch up. If not, there must be something peculiar about this one sample of ADS1112.
My question is if anyone has heard of a failure mode where the ADC reads 0 in all registers but that can be resolved by power cycling.
