NAME
1
VDD1
High-side power
High-side power supply.(1)
2
IN
Analog input
Common analog input pin for window comparator 1 and 2.
3
REF
Analog input
Reference pin that defines the trip threshold for window comparator 1. The voltage
on this pin also affects the hysteresis of comparator Cmp0 as explained in the
Reference Input section. This pin is internally connected to a 100-μA current source.
Connect a resistor from REF to GND1 to define the trip threshold, and a capacitor
from REF to GND1 to filter the reference voltage. For best transient noise immunity,
place the capacitor as closely to the pin as possible. This pin can also be driven by
an external voltage source.
4
GND1
High-side ground
High-side ground.
5
GND2
Low-side ground
Low-side ground.
6
OUT1
Digital output
Open-drain output of window comparator 1. Connect to an external pullup resistor or
leave unconnected (floating) when not used.
7
OUT2
Digital output
Open-drain output of window comparator 2. Connect to an external pullup resistor or
leave unconnected (floating) when not used.
8
VDD2
Low-side power
Low-side power supply.(1)
