The selection of the external capacitor is determined by the desired characteristics of the appli-
cation. These include
• Input Voltage Range (widest range of all input channels)
• Conversion Time
• Programmable Current Source Output Values
The selection of these values should be done to minimize the time between a comparator trip
(ADCIF bit is set) to the ADTMR overflow (OVFIF is set). This ensures that the entire range of
the ADTMR is used for the A/D conversion process.
The equation for selecting the ramp capacitor value is:

time, and full scale voltage measurement.
This capacitor on the CDAC pin should have a low voltage-coefficient as found in teflon, polypro-
pylene, or polystyrene capacitors, for optimum results. This external capacitor must be dis-
charged at the beginning of each conversion cycle by setting the ADRST bit (ADCON0<1>). The
time for the ADRST bit to be set depends on the characteristics of the external capacitor for a
complete discharge.
