23.0
The Analog-to-Digital (A/D) Converter module in the
PIC18F66K80 family of devices has eight inputs for the
28-pin devices, 11 inputs for the 40/44-pin and 64-pin
devices. This module allows conversion of an analog
input signal to a corresponding 12-bit digital number.
The module has these registers:
• A/D Control Register 0 (ADCON0)
• A/D Control Register 1 (ADCON1)
• A/D Control Register 2 (ADCON2)
• A/D Port Configuration Register 1 (ANCON0)
• A/D Port Configuration Register 2 (ANCON1)
• ADRESH (the upper, A/D Results register)
• ADRESL (the lower, A/D Results register)
The ADCON0 register, shown in
trols the operation of the A/D module. The ADCON1
register, shown in
reference and special trigger selection. The ADCON2
register, shown in
clock source and programmed acquisition time and
justification.

Preliminary
PIC18F66K80 FAMILY
23.1
The converter in PIC18F66K80 family devices is
implemented as a differential A/D where the differential
voltage between two channels is measured and
converted to digital values (see
The converter also can be configured to measure a
voltage from a single input by clearing the CHSN bits
(ADCON1<2:0>). With this configuration, the negative
channel input is connected internally to AV
Figure
FIGURE 23-1:
Differential conversion feeds the two input channels to
a unity gain differential amplifier. The positive channel
input is selected using the CHS bits (ADCON0<6:2>)
and the negative channel input is selected using the
CHSN bits (ADCON1<2:0>).
The output from the amplifier is fed to the A/D Con-
verter, as shown in
available on the ADRESH and ADRESL registers. An
additional bit indicates if the 12-bit result is a positive or
negative value.
FIGURE 23-2:
In the Single Channel Measurement mode, the
negative input is connected to A
CHSN bits (ADCON1<2:0>).
