EN (Pin 1): Enable Control Pin. An internal pull-up resistor
of 46k defines the pin’s impedance and will turn the part off
if the pin is unconnected. When the pin is pulled low, the
part is enabled.
DGND (Pin 2): Digital Ground Reference for Enable Pin.
This pin is normally connected to ground.
INR (Pin 3): Red Channel Input. This pin has a nominal
impedance of 400k
termination resistor.
AGND (Pin 4): Analog Ground for 370 Gain Resistor of
Red Channel Amplifier.
ING (Pin 5): Green Channel Input. This pin has a nominal
impedance of 400k
termination resistor.
AGND (Pin 6): Analog Ground Shared for the 370 Gain
Resistors of both Green and Blue Channel Amplifiers.
Additional resistance at this pin will increase the crosstalk
between the green and blue channels.
INB (Pin 7): Blue Channel Input. This pin has a nominal
impedance of 400k
termination resistor.
