The A/D conversion time per bit is defined as T
A/D conversion requires 9.5 T
The source of the A/D conversion clock is software
selectable. The four possible options for T
• 2 T
• 8 T
• 32 T
• Internal RC oscillator
For correct A/D conversions, the A/D conversion clock

These values violate the minimum required T
For faster conversion times, the selection of another clock source is recommended.
When device frequency is greater than 1 MHz, the RC A/D conversion clock source is recommended for

The ADCON1 and TRISA registers control the
operation of the A/D port pins. The port pins that are
desired as analog inputs must have their correspond-
ing TRIS bits set (input). If the TRIS bit is cleared

The A/D operation is independent of the state of the
