The desired resolution can be selected using the BITS bit in the ADCON1 register. If the BITS bit is set to “1”
(10-bit conversion accuracy), the A/D conversion result is stored in the bit 0 to bit 9 in the ADi register (i = 0 to
7). If the BITS bit is set to “0” (8-bit conversion accuracy), the A/D conversion result is stored in the bit 0 to bit
7 in the ADi register.
If the SMP bit in the ADCON2 register is set to “1” (with sample-and-hold), the conversion speed per pin is
increased to 28 φAD cycles for 8-bit resolution or 33 φAD cycles for 10-bit resolution. Sample and Hold is
effective in all operating modes. Select whether or not to use the Sample and Hold function before starting A/D
conversion.
In one-shot and repeat modes, the ANEX0 and ANEX1 pins can be used as analog input pins. Use the OPA1 to
OPA0 bits in the ADCON1 register to select whether or not use ANEX0 and ANEX1.
The A/D conversion results of ANEX0 and ANEX1 inputs are stored in the AD0 and AD1 registers,
respectively.
Multiple analog inputs can be amplified using a single external op-amp via the ANEX0 and ANEX1 pins. Set
the OPA1 to OPA0 bits in the ADCON1 register to “11b” (external op-amp connection mode). The inputs from
ANi (i = 0 to 7)
it back to the ANEX1 pin. The A/D conversion result is stored in the corresponding ADi register. The A/D
conversion speed depends on the response characteristics of the external op-amp. Figure 18.10 shows an
example of How to Connect the Pins in External Op-Amp.
