PIC16F/LF1826/27
15.1
When configuring and using the ADC the following
functions must be considered:
• Port configuration
• Channel selection
• ADC voltage reference selection
• ADC conversion clock source
• Interrupt control
• Result formatting
15.1.1
The ADC can be used to convert both analog and
digital signals. When converting analog signals, the I/O
pin should be configured for analog by setting the
associated
Section 12.0 “I/O Ports” for more information.
15.1.2
There are up to 14 channel selections available:
• AN<11:0> pins
• DAC Output
• FVR (Fixed Voltage Reference) Output
Refer to Section 16.0 “Digital-to-Analog Converter
(DAC) Module” and Section 14.0 “Fixed Voltage
Reference (FVR)” for more information on these
channel selections.
The CHS bits of the ADCON0 register determine which
channel is connected to the sample and hold circuit.
When changing channels, a delay is required before
starting the next conversion. Refer to Section 15.2
“ADC Operation” for more information.
15.1.3
The ADPREF bits of the ADCON1 register provides
control of the positive voltage reference. The positive
voltage reference can be:
• V
• V
• FVR 2.028V
• FVR 4.096V (Not available on LF devices)
The ADNREF bits of the ADCON1 register provides
control of the negative voltage reference. The negative
voltage reference can be:
• V
• V
See Section 14.0 “Fixed Voltage Reference (FVR)”
for more details on the fixed voltage reference.

The source of the conversion clock is software select-
able via the ADCS bits of the ADCON1 register. There
are seven possible clock options:
• F
• F
• F
• F
• F
• F
• F
The time to complete one bit conversion is defined as
T
ods as shown in Figure 15-2.
For correct conversion, the appropriate T
must be met. Refer to the A/D conversion requirements
in Section 29.0 “Electrical Specifications” for more
information. Table 15-1 gives examples of appropriate
ADC clock selections.
