increases gain.

2

–IN1

CH1 Negative Input.

3

+IN1

CH1 Positive Input.

4GND1

Ground.

5GND2

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, 1.67 V = 30 dB/V.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily

accumulate on the human body and test equipment and can discharge without detection. Although

the AD605 features proprietary ESD protection circuitry, permanent damage may occur on devices

subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are

recommended to avoid performance degradation or loss of functionality.
