48.8 DESIGN TIPS
Question 1: Why is my voltage reference not what I expect?
Answer: Any variation of the voltage reference source will translate directly onto the
CV
REF pin. Also, ensure that you have correctly calculated the voltage divider,
which generates the voltage reference.
Question 2: Why is my voltage reference not at the expected level when I connect CVREF
into a low-impedance circuit?
Answer: The voltage reference module is not intended to drive large loads. A buffer must
be used between the CV
REF pin and the load of the PIC24F device (see
Figure 48-8).
