Label Pin # Function Typical Connection
D− 4
Diode Return Current
Sink To all Diode Junction Cathodes using a star
connection to pin. Must float when not used.
ADD0–ADD1 10, 6
User-Set SMBus (I 2 C)
Address Inputs
Ground (Low, “0”), V

(High, “1”) or open
(“TRI-LEVEL”)
GND 7, 8 Power Supply Ground Ground
NC 9, 13, 15
Manufacturing test pins. Left floating. PC board traces may be routed
through the pads for these pins, although the
components that drive these traces should share
the same supply as the LM83 so that the Absolute
Maximum Rating, Voltage at Any Pin, is not
violated.
