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 Isolation Between Red

and Green Channel Inputs. The AGND pins have ESD

protection and therefore should not be connected to

potentials outside the power supply range.

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 for Isolation Between Green

and Blue Channel Inputs. The AGND pins have ESD protec-

tion and therefore should not be connected to potentials

outside the power supply range.

INB (Pin 7): Blue Channel Input. This pin has a nominal

impedance of 400kΩ and does not have any internal

termination resistor.

V– (Pin 8): Negative Supply Voltage. V– 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.

V– (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 the buffered

output of the blue channel input.

V+ (Pin 11): Positive Supply Voltage for Blue and Green

Channel Output Stages. V+ pins are not internally con-

nected to each other, and must all be connected externally.

Proper supply bypassing is necessary for best perfor-

mance. See the Applications Information section.

OUTG (Pin 12): Green Channel Output. It is the buffered

output of the green channel input.

V– (Pin 13): Negative Supply Voltage for Green and Red

Channel Output Stages. V – pins are not internally con-

nected to each other, and must all be connected externally.

Proper supply bypassing is necessary for best perfor-

mance. See the Applications Information section.

OUTR (Pin 14): Red Channel Output. It is the buffered

output of the red channel input.

V+ (Pin 15): Positive Supply Voltage for Red 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.

V+ (Pin 16): Positive Supply Voltage. V+ 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.
