3.0 PIN DESCRIPTIONS
An overview of the pin functions are described in
Section 3.1 “Analog Output Voltage Pin (V
OUT
)”
through Section 3.7 “Exposed Pad (EP)”. The
descriptions of the pins are listed in Table 3-1.

Note 1: The DFN package has a contact on the bottom of the package. This contact is conductively connected to
the die substrate, and therefore should be unconnected or connected to the same ground as the device’s
V
SS
pin.
