Overdriven Output Recovery

Enable/Disable Response

Large-Signal Transient Response

EN (Pin 1): Enable Control Pin. The part is enabled when

this pin is pulled low. An internal pull-up resistor of 40k

will turn the part off if this pin is unconnected.

GND (Pin 2): Ground Reference for Enable Pin (Pin 1)

and Bias Control Voltage Pin (Pin 16). This pin must be

connected externally to ground.

IN R (Pin 3): Red Channel Input. This pin has a nominal

impedance of 200kΩ with input bias circuit inactive,

Pin 16 open.

GND R (Pin 4): Ground of Red Channel Amplifier. This pin

is not internally connected to other ground pins and must

be connected externally to ground.

IN G (Pin 5): Green Channel Input. This pin has a nomi-

nal impedance of 200kΩ with input bias circuit inactive,

Pin 16 open.

GND G (Pin 6): Ground of Green Channel Amplifier. This

pin is not internally connected to other ground pins and

must be connected externally to ground.

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

impedance of 200kΩ with input bias circuit inactive,

Pin 16 open.

GND B (Pin 8): Ground of Blue Channel Amplifier. This

pin is not internally connected to other ground pins and

must be connected externally to ground.
