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 400kΩ and does not have any internal
termination resistor.
AGND (Pin 4): Analog Ground for 370Ω Gain Resistor of
Red Channel Amplifier.
ING (Pin 5): Green Channel Input. This pin has a nominal
impedance of 400kΩ and does not have any internal
termination resistor.
AGND (Pin 6): Analog Ground Shared for the 370Ω 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 400kΩ and does not have any internal
termination resistor.

pins are not
internally connected to each other, and must all be con-
nected externally. Proper supply bypassing is necessary
for best performance. See the Applications Information
section.

(Pin 9): Negative Supply Voltage for Blue Channel
Output Stage. V

pins are not internally connected to each
other, and must all be connected externally. Proper supply
bypassing is necessary for best performance. See the
Applications Information section.
OUTB (Pin 10): Blue Channel Output. It is twice the blue
channel input, and performs optimally with a 150Ω load (a
double terminated 75Ω cable).
