The auxiliary ADC has three external input pins (labeled AIN3
to AIN5) as well as an internal connection to the on-chip tem-
perature sensor. All inputs to the auxiliary ADC are single-ended
inputs referenced to the AGND on the part. Channel selection
bits in the ADC1CON SFR detailed in Table VII allow selection
of one of four inputs.
Two input multiplexers switch the selected input channel to the
on-chip buffer amplifier in the case of the primary ADC and
directly to the
-
modulator input in the case of the auxiliary
ADC. When the analog input channel is switched, the settling
time of the part must elapse before a new valid word is available
from the ADC.

Auxiliary ADC
The auxiliary ADC is intended to convert supplementary inputs
such as those from a cold junction diode or thermistor. This ADC
is not buffered and has a fixed input range of 0 V to 2.5 V (assuming
an external 2.5 V reference). The single-ended inputs can be driven
from AIN3, AIN4, or AIN5 pins, or directly from the on-chip
temperature sensor voltage. A block diagram of the auxiliary ADC
is shown in Figure 8.
Analog Input Channels
The primary ADC has four associated analog input pins (labeled
AIN1 to AIN4) that can be configured as two fully differential input
channels. Channel selection bits in the ADC0CON SFR detailed
in Table VI allow three combinations of differential pair selection
as well as an additional shorted input option (AIN2–AIN2).
