DESCRIPTION

NAME

NO.

Noninverting Comparator Input. The +IN has a common-mode voltage range from 1 V above

the negative rail to, and including, the positive rail. Internal ESD diodes, connected from the

+IN

+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.

Inverting Comparator Input. The

−IN has a common-mode voltage range from 1 V above the

negative rail to, and including, the positive rail. Internal ESD diodes, connected from the

−IN

-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.

Ground. 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

GND

ceramic capacitor to ground. The internal reference output voltage is referenced to this pin.

GND is the die substrate connection.

Comparator Output. 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

OUT

may be taken to a maximum of +12 V with respect to the ground pin, irrespective of supply

voltage.

Negative Hysteresis pin. This pin sets the lower trip voltage VIL. The common mode range is

HYSTN

from 1V above the negative rail to VCC. The input signal must fall below VIL for the

comparator to switch from high to low state.

Positive Hysteresis pin. This pin sets the upper trip voltage VIH. The common mode range is

HYSTP

from 1V above the negative rail to VCC. The input signal must rise above VIH for the

comparator to switch from low to high state.

Reference Voltage Output pin. This is the output pin of a 2.048-V band gap precision

REF

reference.

Positive Supply Terminal. The supply voltage range is 2.7 V to 12 V. Decouple this pin with

V+

0.1-

μF ceramic capacitor to ground.
