Description
Channel 1 Negative Signal Input to DSX1.
Channel 1 Positive Signal Input to DSX1.
Channel 1 Preamplifier Output.
Channel 1 Preamplifier Feedback Pin.
Channel 1 Preamplifier Positive Input.
Channel 1 Signal Ground. When this pin is connected to positive supply, Preamplifier 1 shuts down.
Channel 2 Signal Ground. When this pin is connected to positive supply, Preamplifier 2 shuts down.
Channel 2 Preamplifier Positive Input.
Channel 2 Preamplifier Feedback Pin.
Channel 2 Preamplifier Output.
Channel 2 Positive Signal Input to DSX2.
Channel 2 Negative Signal Input to DSX2.
Channel 2 Gain Control Input and Power-Down Pin. If this pin is grounded, the device is off; otherwise, positive
voltage increases gain.
Input to this pin defines the common mode of the output at OUT1 and OUT2.
Channel 2 Signal Output.
Ground.
Positive Supply.
Negative Supply.
Negative Supply.
Positive Supply.
Ground.
Channel 1 Signal Output.
Input to this pin sets gain scaling for both channels to 2.5 V = 20 dB/V and 1.67 V = 30 dB/V.
Channel 1 Gain Control Input and Power-Down Pin. If this pin is grounded, the device is off; otherwise, positive
voltage increases gain.
