LM1269NA Amplifier DIP-24
The LM1269NA Amplifier DIP-24 is an advanced RGB video preamplifier designed for high-fidelity CRT displays and low-cost bus-controlled monitors. Integrating a 110MHz bandwidth preamplifier, the device allows comprehensive control of gain, contrast, brightness, and bias through an I2C-compatible interface. The amplifier features four external 8-bit DACs, enabling precise software-controlled video parameter adjustments. Black level clamping is performed directly on the AC-coupled input, eliminating the need for additional capacitive components, ensuring a simplified and reliable design.
Features:
- 110 MHz bandwidth for high-resolution video signal amplification.
- I2C compatible interface for digital control of parameters.
- RGB video amplifier system with three channels.
- On-screen display (OSD) support for overlay graphics.
- Integrated digital-to-analog converters (DACs) for precise adjustments.
- CMOS technology for low power consumption.
- Voltage clamping and low impedance reference for signal stability.
