Description
1
–DSX1
Channel 1 Negative Signal Input to DSX1.
2
+DSX1
Channel 1 Positive Signal Input to DSX1.
3
PAO1
Channel 1 Preamplifier Output.
4
FBK1
Channel 1 Preamplifier Feedback Pin.
5
PAI1
Channel 1 Preamplifier Positive Input.
6
COM1
Channel 1 Signal Ground. When this pin is connected to positive supply, Preamplifier 1 shuts down.
7
COM2
Channel 2 Signal Ground. When this pin is connected to positive supply, Preamplifier 2 shuts down.
8
PAI2
Channel 2 Preamplifier Positive Input.
9
FBK2
Channel 2 Preamplifier Feedback Pin.
10
PAO2
Channel 2 Preamplifier Output.
11
+DSX2
Channel 2 Positive Signal Input to DSX2.
12
–DSX2
Channel 2 Negative Signal Input to DSX2.
13
VGN2
Channel 2 Gain Control Input and Power-Down Pin. If this pin is grounded, the device is off; otherwise, positive
voltage increases gain.
14
VOCM
Input to this pin defines the common mode of the output at OUT1 and OUT2.
15
OUT2
Channel 2 Signal Output.
16
GND2
Ground.
17
VPOS
Positive Supply.
18
VNEG
Negative Supply.
19
VNEG
Negative Supply.
20
VPOS
Positive Supply.
21
GND1
Ground.
22
OUT1
Channel 1 Signal Output.
23
VREF
Input to this pin sets gain scaling for both channels to 2.5 V = 20 dB/V and 1.67 V = 30 dB/V.
24
VGN1
Channel 1 Gain Control Input and Power-Down Pin. If this pin is grounded, the device is off; otherwise, positive
voltage increases gain.
