Description
Temperature Sensor Analog Output. Enabled when the internal reference is turned on
(PDREF = PDBUF = low). See the Temperature Sensor section.
Reference Buffer Input. When using an external reference with the internal reference buffer
(PDBUF = low, PDREF = high), applying 2.5 V on this pin produces 5 V on the REF pin.
See the Voltage Reference Input section.
Internal Reference Power-Down Input.
When low, the internal reference is enabled.
When high, the internal reference is powered down, and an external reference must be used.
Internal Reference Buffer Power-Down Input.
When low, the buffer is enabled (must be low when using internal reference).
When high, the buffer is powered-down.
