The A/D conversion time per bit is defined as T
A/D conversion requires 9.0 T
The source of the A/D conversion clock is software
selectable. The seven possible options for T
• 2 T
• 4 T
• 8 T
• 16 T
• 32 T
• 64 T
• Internal A/D module RC oscillator (2-6 s)
For correct A/D conversions, the A/D conversion clock

greater than 6.4 s.

The ADCON1, ANSEL, TRISA, and TRISB registers
control the operation of the A/D port pins. The port pins
that are desired as analog inputs must have their cor-
responding TRIS bits set (input). If the TRIS bit is
cleared (output), the digital output level (V
will be converted.
The A/D operation is independent of the state of the
CHS<2:0> bits and the TRIS bits.

2: Analog levels on any pin that is defined as

configured as analog input channels will
read as cleared (a low level). Pins config-
ured as digital inputs will convert an ana-
log input. Analog levels on a digitally
configured input will not affect the
conversion accuracy.
a digital input (including the RA4:RA0 and
RB7:RB6 pins), may cause the input
buffer to consume current out of the
device specification.
