Mnemonic Description
AS
Logic Input. Address select input that selects one
of three I2C addresses for the AD7414/AD7415 (see
Table 4). Recommend a pull-up or pull-down
resistor of 1 kΩ.
GND
Analog and Digital Ground.
VDD
Positive Supply Voltage, 2.7 V to 5.5 V.
SDA
Digital I/O. Serial bus bidirectional data. Open-
drain output.
ALERT
AD7414 Digital Output. Overtemperature
indicator becomes active when temperature
exceeds THIGH. Open-drain output.
SCL
Digital Input. Serial bus clock.
