The analog-to-digital (A/D) converter module has
twelve analog inputs for the PIC17C75X devices and
sixteen for the PIC17C76X devices.
The analog input charges a sample and hold capacitor.
The output of the sample and hold capacitor is the input
into the converter. The converter then generates a dig-
ital result of this analog level via successive approxima-
tion. This A/D conversion of the analog input signal,
results in a corresponding 10-bit digital number.
The analog reference voltages (positive and negative
supply) are software selectable to either the device’s
supply voltages (AV

The A/D converter has a unique feature of being able
to operate while the device is in SLEEP mode. To oper-
ate in SLEEP, the A/D clock must be derived from the
A/D’s internal RC oscillator.
The A/D module has four registers. These registers
are:
• A/D Result High Register (ADRESH)
• A/D Result Low Register (ADRESL)
• A/D Control Register0 (ADCON0)
• A/D Control Register1 (ADCON1)
The ADCON0 register, shown in Register 16-1, con-
trols the operation of the A/D module. The ADCON1
register, shown in Register 16-2, configures the func-
tions of the port pins. The port pins can be configured
as analog inputs (RG3 and RG2 can also be the volt-
age references), or as digital I/O.
