NTE7139
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:
No External Heatsink Required
Black Current Measurement Output for Automatice Black Current Stabilization (ABS)
Internal 2.5V Reference Circuit
Internal Protection Against Positive Apperaing CRT Flashover Discharges
Single Supply Voltage of 200V
Simple Application with a Variety of Color Decoders
Controlled Switch–Off Behaviour
Absolute Maximum Ratings:

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 100
μ
C.
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 100
μ
C.
Note 4. Human body model: equivalent to discharging a 100pF capacitor through a 1.5k
resistor.
Note 5. Machine model: equivalent to discharging a 200pF capacitor through a 0
resistor.
