REFOUT
Reference Input (REFIN)/Reference Output (REFOUT). The on-chip reference
of 2.5 V is available on this pin for external use if the REF SELECT pin is set to
logic high. Alternatively, the internal reference can be disabled by setting
the REF SELECT pin to logic low, and an external reference of 2.5 V can be
applied to this input (see the Internal/External Reference section).
Decoupling is required on this pin for both the internal and external
reference options. A 10 μF capacitor should be applied from this pin to
ground close to the REFGND pins.

Reference Buffer Output Force/Sense Pins. These pins must be connected
together and decoupled to AGND using a low ESR, 10 μF ceramic capacitor.
The voltage on these pins is typically 4.5 V.
