LM1205N
₦2,700.00
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

The LM1205 LM1207 is a very high frequency video amplifi-
er system intended for use in high resolution RGB monitor
applications In addition to the three matched video amplifi-
ers the LM1205 LM1207 contains three gated single end-
ed input black level clamp comparators for brightness con-
trol three matched DC controlled attenuators for contrast
control and three DC controlled sub-contrast attenuators
providing gain trim capability for white balance All DC con-
trol inputs offer high input impedance and an operation
range from 0V to 4V for easy interface to bus controlled
alignment systems The LM1205 LM1207 also contains a
blanking circuit which clamps the video output voltage dur-
ing blanking to within 0 1V above ground This feature pro-
vides blanking capability at the cathodes of the CRT A spot
killer is provided for CRT phosphor protection during power-
down
