Silicon Errata Issues
1. Module: ADC
1.1 Operation with FOSC/2
The ADC is not functional when the ADCS<2:0>
bits of ADCON1 select the FOSC/2 frequency.
Work around
Use the FRC selection which provides a valid TAD
time regardless of the system clock frequency.
Affected Silicon Revisions
1.2 ADC Offset
The offset error exceeds the data sheet
specification when the time between conversions
is greater than 100 us.
Work around
The time dependent error is insignificant when the
time between conversions is less than 100 us.
When the time between conversions is greater
than 100 us, take two back-to-back ADC
conversions and discard the results of the first
conversion.
Affected Silicon Revisions
Note: This document summarizes all silicon
errata issues from all revisions of silicon,
previous as well as current. Only the
issues indicated by the shaded column in
the following tables apply to the current
