When the A/D converter is not used, the VCUT bit in the AD0CON1 register isolates the resistor ladder of
the A/D converter from the reference voltage input pin (V
off any current flow into the resistor ladder from the V
When using the A/D converter, set the VCUT bit to "1" (V
the AD0CON0 register to "1" (A/D conversion started). Do not set the ADST bit and VCUT bit to "1"
simultaneously, nor set the VCUT bit to "0" (no V
bit does not affect the V
For perfect A/D converter performance, complete internal capacitor (C) charging, shown in Figure 18.8,

(0.1/1024) means that A/D precision drop, due to insufficient capacitor charge, is held to 0.1LSB at time of A/
D conversion in the 10-bit mode. Actual error, however, is the value of absolute precision added to 0.1LSB.
When ØAD = 10 MHz, T = 0.3 s in the A/D conversion mode with the sample and hold function. Output
impedance (R
Thus, the allowable output impedance of the sensor equivalent circuit, making the precision (error)
0.1LSB or less, is approximately 13.9 k
