Description
CH1 Negative Signal Input to DSX1.
CH1 Positive Signal Input to DSX1.
CH1 Preamplifier Output.
CH1 Preamplifier Feedback Pin.
CH1 Preamplifier Positive Input.
CH1 Signal Ground; when connected to positive supply, Preamplifier1 will shut down.
CH2 Signal Ground; when connected to positive supply, Preamplifier2 will shut down.
CH2 Preamplifier Positive Input.
CH2 Preamplifier Feedback Pin.
CH2 Preamplifier Output.
CH2 Positive Signal Input to DSX2.
CH2 Negative Signal Input to DSX2.
CH2 Gain-Control Input and Power-Down Pin. If grounded, device is off,
otherwise positive voltage increases gain.
Input to this pin defines common-mode of output at OUT1 and OUT2.
