External Reference
It is important to understand that the reference voltage plays a fundamental
part in the conversion process. Changes in the value of the reference voltage
are reflected in the full-scale range of the device. The variation in voltage for
the reference should, ideally, contribute less than 1/2 an LSB of error to the
total conversion process.
External reference voltages can be supplied via J6; see Section 3

Connector Pin and Function Assignments
for pinout details. The jumper
configuration for this option is given in the following figure.
Under no circumstance should the external voltage exceed the
supply voltage by more than 0.3 V.
