3.0 REFERENCE VOLTAGE
The difference in the voltages applied to the V
REF+
and
V
REF
defines the analog input span (the difference between
the voltage applied between two multiplexer inputs or the
voltage applied to one of the multiplexer inputs and analog
ground), over which 4095 positive and 4096 negative codes
exist. The voltage sources driving V
REF+
or V
REF
must have
very low output impedance and noise. The circuit in Figure
16 is an example of a very stable reference appropriate for
use with the device.
