Description

1

VGN1

CH1 Gain-Control Input and Power-Down Pin. If grounded, device is off; otherwise, positive voltage increases gain.

2

−IN1

CH1 Negative Input.

3

+IN1

CH1 Positive Input.

4

GND1

Ground.

5

GND2

Ground.

6

+IN2

CH2 Positive Input.

7

−IN2

CH2 Negative Input.

8

VGN2

CH2 Gain-Control Input and Power-Down Pin. If grounded, device is off; otherwise, positive voltage increases gain.

9

VOCM

Input to This Pin Defines Common-Mode Voltage for OUT1 and OUT2.

10

OUT2

CH2 Output.

11

FBK2

Feedback Pin That Selects Gain Range of CH2.

12

VPOS

Positive Supply.

13

VPOS

Positive Supply.

14

FBK1

Feedback Pin That Selects Gain Range of CH1.

15

OUT1

CH1 Output.

16

VREF

Input to This Pin Sets Gain Scaling for Both Channels: 2.5 V = 20 dB/V and 1.67 V = 30 dB/V.
