Description
Primary Analog Input with a Range of 0 V to 2.5 V.
Temperature Sensor Voltage Output.
Reference Input Voltage. The reference output and the reference buffer input.
This pin allows the choice of internal or external voltage references. When LOW, the on-chip
reference is turned on. When HIGH, the internal reference is switched off and an external reference
must be used.
This pin allows the choice of buffering an internal or external reference with the internal buffer.
When LOW, the buffer is selected. When HIGH, the buffer is switched off.
