3.0 PIN DESCRIPTIONS
The descriptions of the pins are listed Ta ble 3- 1.
TABLE 3-1: PIN FUNCTION TABLE
3.1 Power Ground Pin (GND)
GND is the system ground pin.
3.2 Output Voltage Pin (V
OUT
)
The sensor output can be measured at V
OUT
. The
voltage range over the operating temperature range for
the MCP9700/9700A is 100 mV to 1.75V and for the
MCP9701/9701A, 200 mV to 3V .
3.3 Power Supply Input (V
DD
)
The operating voltage as specified in the “DC
Electrical Characteristics” table is applied to V
DD
.
3.4 No Connect Pin (NC)
This pin is not connected to the die. It can be used to
improve thermal conduction to the package by
connecting it to a Printed Circuit Board (PCB) trace
from the thermal source.
