Description
The +IN has a common-mode voltage range from 1V above the negative rail to, and including,
the positive rail. Internal ESD diodes, connected from the +IN pin to the rails, protect the input
stage from overvoltage. If the input voltage exceeds the rails, the diodes turn on and clamp
the input to a safe level.
The −IN has a common-mode voltage range from 1V above the negative rail to, and including,
the positive rail. Internal ESD diodes, connected from the −IN pin to the rails, protects the
input stage from overvoltage. If the input voltage exceeds the rails, the diodes turn on and
clamp the input to a safe level.
This pin may be connected to a negative DC voltage source for applications requiring a dual
supply. If connected to a negative supply, decouple this pin with 0.1 µF ceramic capacitor to
ground. The internal reference output voltage is referenced to this pin. GND is the die
substrate connection.
The output is an open-collector. It can drive voltage loads by using a pullup resistor, or it can
drive current loads by sinking a maximum output current. This pin may be taken to a
maximum of +12V with respect to the ground pin, irrespective of supply voltage.
This pin sets the lower trip voltage V

high to low state.
This pin sets the upper trip voltage V
negative rail to V
low to high state.
This is the output pin of a 2.048V band gap precision reference.
