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/°C
Doubly Balanced Demodulation

Replaces:
ECG791, GEIC-33, GEIC-231, SK3149, TCG791
