PIC16(L)F1782/1783
3. Module: Comparator
3.1 No Low-Power, No Low-Speed Mode
The comparator operation in Low-Power, Low-
Speed mode (CxSP = 0) may not perform properly.
Work around
Use the comparator in High-Power mode.
Affected Silicon Revisions
3.2 Typical Offset Performance
CMRR performance for the range of V
SS + 1V to
V
DD - 1V is better than specified in the data
sheet.
Work around
See Figure 6 and Figure 7.
