1.4.4 Unreliable Conversion Results with Fast Falling Slew Rate
When the ADC input falls by greater than 3.2V, with a slew rate faster than -11 V/μs, the following ADC conversion will have the Most Significant bit (MSb) improperly set. This is likely to happen when the ADC input channel is switched from one with a high-level input to another with a low-level input.
Work around
When switching between input channels, discard the first conversion result after the switch. Subsequent conversions will not be affected.
