Negative Supply Terminal

23

NC

No Connect. Leave pin unconnected.

Negative Supply Terminal

25

GND

Digital Ground

26

QA

One of two complementary outputs for Channel A. QA will be at logic high if the analog voltage at the

noninverting input is greater than the analog voltage at the inverting input (provided the comparator is

in the compare mode). See the LEA description (Pin 30) for more information.

27

QA

One of two complementary outputs for Channel A. QA will be at logic low if the analog voltage at the

noninverting input is greater than the analog voltage at the inverting input (provided the comparator is

in the compare mode). See the LEA description (Pin 30) for more information.

GND

Digital Ground

29

NC

No Connect. Leave pin unconnected.

30

LEA

One of two complementary inputs for Channel A Latch Enable. In the compare mode (logic high), the

output will track changes at the input of the comparator. In the latch mode (logic low), the output will

reflect the input state just prior to the comparator’s being placed in the latch mode. LEA must be driven

in conjunction with LEA.
