Function Pin Descriptions (Cont.)
SSDONE
This pin is an open drain device; connect a pull up
resistor to VCC for SSDONE function.
REFIN
This pin provides a external reference voltage instead
of the internal 0.6V reference. The REFIN pin is pulled
to 5V internally. If the REFIN voltage is less than 4V,
the external voltage is used.
