Function

To second Diode Anode. Connected to remote discrete diode-
connected transistor junction or to the diode-connected
transistor junction on a remote IC whose die temperature is
being sensed. A capacitor is not required between D2+ and
D-. A 100 pF capacitor between D2+ and D- can be added
and may improve perfomance in noisy systems. Float this pin
if this thermal diode is not used.
