NTE791
Integrated Circuit
TV Chroma Amplifier Demodulator
Description:
Compromised of an independent 2–stage chroma amplifier, chroma demodulators, resistor matrix,
and color difference amplifiers. The NTE791 monolithic silicon integrated circuit is one of two blocks
required for a complete color television receiver chroma system.
The chroma amplifiers contain the necessary circuitry for automatic chroma control and color–killer
sensing and control. The demodulators and resistor matrix reconstruct the G–Y color chain to bypass
unwanted harmonics. The high–level emitter follower outputs are current limited for short–circuit
protection.
Features:
DC Chroma Gain Control
Improved Filtering for Harmonic Reduction
Output Short–Circuit Current Limiting
Self–Contained Bias Regulator
Low Thermal Drift, Typically 1mV/
