I have WDT in circuit and the supply is provided by a DC/DC converter that its output is a regulated 5VDC,I used 100n and 10 uf TAN capacitors for power pins of ADC and the supply filtering is good.
But in noisy field I think it is difficult to use sigma delta ,and the ADC lost its sequence.
Only with power off and then on after several seconds everything becomes ok.
