Pin Functions

PIN TYPE DESCRIPTION
NAME DSBGA SC70
GND — 2 GND Device substrate and die attach paddle, connect to power supply negative terminal. For optimum thermal conductivity to the PC board ground plane, pin 2 must be grounded. This pin may also be left floating.
GND A2 5 GND Device ground pin, connect to power supply negative terminal.
NC A1 1 — NC (pin 1) must be left floating or grounded. Other signal traces must not be connected to this pin.
VO B1 3 Analog Output Temperature sensor analog output
V+ B2 4 Power Positive power supply pin
