Table 3. Pin Function Descriptions
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.
