OVERVIEW
The MSC1211/12/13/14 ADC structure is shown in
Figure 12. The figure lists the components that make up
the ADC, along with the corresponding special function
register (SFR) associated with each component.
ADC INPUT MULTIPLEXER
The input multiplexer provides for any combination of
differential inputs to be selected as the input channel, as
shown in Figure 13. For example, if AIN0 is selected as the
positive differential input channel, then any other channel
can be selected as the negative differential input channel.
With this method, it is possible to have up to eight fully
differential input channels with common connections
between them. It is also possible to switch the polarity of
the differential input pair to negate any offset voltages. In
addition, current sources are supplied that will source or
sink current to detect open or short circuits on the pins.
TEMPERATURE SENSOR
On-chip diodes provide temperature sensing capability.
When the configuration register for the input MUX is set to
all 1s, the diodes are connected to the inputs of the ADC.
All other channels are open.
BURNOUT DETECT
When the Burnout Detect (BOD) bit is set in the ADC
control configuration register (ADCON0 DCh), two current
sources are enabled. The current source on the positive
input channel sources approximately 2
A of current. The
current source on the negative input channel sinks
approximately 2
A. The current sources allow for the
detection of an open circuit (full-scale reading) or short
circuit (small differential reading) on the selected input
differential pair. The buffer should be on for sensor burnout
detection.
