Integrated Circuit
Video Output Amplifier
Description:
The NTE7139 is a monolithic video output amplifier with a 6MHz bandwidth in a 9–Lead Staggered
SIP type medium power package. This device uses high–voltage DMOS technology and is intended
to drive the cathode of a CRT. To obtain maximum performance, the amplifier should be used with
black current control.
Features:
D No External Heatsink Required
D Black Current Measurement Output for Automatice Black Current Stabilization (ABS)
D Internal 2.5V Reference Circuit
D Internal Protection Against Positive Apperaing CRT Flashover Discharges
D Single Supply Voltage of 200V
D Simple Application with a Variety of Color Decoders
D Controlled Switch–Off Behaviour
Absolute Maximum Ratings: (Voltages referenced to GND (Pin4) unbless otherwise specified)

Note 1. Inputs and output are protected against electrostatic discharge in normal handling. However ,
to be total ly s afe, i t i s d esirabl e t o t ake n ormal p r ecautions a ppropri ate t o h andling M OS d evi ces.
Note 2. The cathode output is protected against peak currents (caused by positive voltage peaks
during high–resistance flash) of 5mA maximum with a charge content of 100µC.
Note 3. The cathode output is also protected against peak currents (caused by positive voltage
peaks during low–resistance flash) of 10mA maximum with a charge content of 100µC.
Note 4. Human body model: equivalent to discharging a 100pF capacitor through a 1.5kΩ resistor.
