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

Note 1. Inputs and output are protected against electrostatic discharge in normal handling. However,
to be totally safe, it is desirable to take normal precautions appropriate to handling MOS devices.
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.
Note 5. Machine model: equivalent to discharging a 200pF capacitor through a 0Ω resistor.
Note 6. External heatsink not required.
