Description

1

−IN

Inverting Input.

2

VOCM

An internal feedback loop drives the output common-mode voltage to be equal to the voltage applied to

the VOCM pin, provided the operation of the amplifier remains linear.

3

V+

Positive Power Supply Voltage.

4

+OUT

Positive Side of the Differential Output.

5

−OUT

Negative Side of the Differential Output.

6

V−

Negative Power Supply Voltage.

7

NC

No Internal Connection.

8

+IN

Noninverting Input.

9

Exposed Paddle Solder exposed paddle on back of package to ground plane or to a power plane.
