Pin No. Mnemonic 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.
