描述 Description

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
