PIN FUNCTIONS EN (Pin 1):
Enable Control Pin. The part is enabled when
IN G (Pin 5):
Green Channel Input. This pin has a nomi- this pin is pulled low. An internal pull-up resistor of 40k nal impedance of 200kΩ with input bias circuit inactive, will turn the part off if this pin is unconnected. Pin 16 open.
GND (Pin 2):
Ground Reference for Enable Pin (Pin 1)
GND G (Pin 6):
Ground of Green Channel Amplifi er. This and Bias Control Voltage Pin (Pin 16). This pin must be pin is not internally connected to other ground pins and connected externally to ground. must be connected externally to ground.
IN R (Pin 3):
Red Channel Input. This pin has a nominal
IN B (Pin 7):
Blue Channel Input. This pin has a nominal impedance of 200kΩ with input bias circuit inactive, impedance of 200kΩ with input bias circuit inactive, Pin 16 open. Pin 16 open.
GND R (Pin 4):
Ground of Red Channel Amplifi er. This pin
GND B (Pin 8):
Ground of Blue Channel Amplifi er. This is not internally connected to other ground pins and must pin is not internally connected to other ground pins and be connected externally to ground. must be connected externally to ground. 6557fa 7
