LM1205N

Description:

The LM1205N is a very high-frequency (130 MHz) RGB video amplifier system with blanking, designed for use in high-resolution RGB monitor applications. It provides exceptional image quality by amplifying and processing red, green, and blue video signals while minimizing noise and distortion. The LM1205N also features blanking capability to prevent unwanted signal output during power-down or retrace intervals, protecting the CRT phosphor.

Key Features:

• Three high-bandwidth video amplifiers (130 MHz) for red, green, and blue video signals
• Matched attenuators for precise contrast control
• Three independent comparators for cutoff and brightness control of each video channel
• High input impedance (0V to 4V DC) for compatibility with various video sources
• Blanking capability at the CRT cathode for display protection
• Capable of driving most CRT driver circuits directly

Technical Specifications:

• Package Type: DIP-28
• Supply Voltage: 10.8V to 13.2V DC
• Operating Temperature Range: -20°C to +80°C
• Video Bandwidth: 130 MHz (typical)
• Differential Gain (g0): ±1 dB (typical)
• Input Impedance: >100 kΩ (typical)
• Output Voltage Swing: Up to 7V peak-to-peak (with slight reduction in bandwidth)

Applications:

• High-resolution RGB CRT monitors
• Professional video displays
• Video processing equipment
• High-performance video amplifiers
