The 8-bit analog-to-digital (A/D) converter module has
five inputs for the PIC16F73/76 and eight for the
PIC16F74/77.
The A/D allows conversion of an analog input signal to
a corresponding 8-bit digital number. The output of the
sample and hold is the input into the converter, which
generates the result via successive approximation. The
analog reference voltage is software selectable to
either the device’s positive supply voltage (V
voltage level on the RA3/AN3/V
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 conversion clock must be
derived from the A/D’s internal RC oscillator.

The A/D module has three registers. These registers
are:
The ADCON0 register, shown in Register 11-1, con-
trols the operation of the A/D module. The ADCON1
register, shown in Register 11-2, configures the func-
tions of the port pins. The port pins can be configured
as analog inputs (RA3 can also be a voltage reference),
or as digital I/O.
Additional information on using the A/D module can be
found in the PICmicro™ Mid-Range MCU Family Ref-
erence Manual (DS33023) and in Application Note,
AN546 (DS00546).
