Description
Voltage Reference Input. Sets the output dc bias voltage. Internally biased to +Vs/2 when left floating. See the
Applications Information section.
Positive Input.
Negative Input.
Power Supply Ground Pin.
Short to Battery Indicator Pin. A logic low indicates an overvoltage condition (short to battery), whereas a logic
high indicates normal operation. An open-drain configuration requires external pull-up resistor.
Video Amplifier Output.
Enable. Connect to +VS or float for normal operation. Connect to GND for device disable.
Positive Power Supply. Bypass this pin with a 0.1 µF capacitor to GND.
Exposed Pad. The exposed pad is located on bottom side of package. The pad is not connected electrically but
should be soldered to a metalized area on the PCB to minimize thermal resistance.
