Description

1

EMIT OUT

Emitter Output – This is the Emitter pin of the output transistor

2

Non-Inverting Input (IN+)

The Non-Inverting Pin of the comparator is give a variable  voltage to compare

3

Inverting Input (IN-)

The Inverting pin is also given a fixed voltage which is compared with the (IN+)

4

Ground (VCC-)

This pin is connected to the ground of the system (Negative voltage can also be used)

5

Balance

This pin can be used to turn off  the DC-offset voltage

6

Balance/Strobe

This pin can be used to turn off the output stage

7

COL OUT

Collector Out – This is the Collector output of the transistor

8

VCC+

Provide the operating voltage for the Op-Amp. For LM311 it is upto +15V
