Overview
The LM2437T/NOPB is a monolithic triple CRT driver designed for color monitor applications. It integrates three high input impedance, wide band amplifiers that directly drive RGB cathodes with an internal gain of -14. The device operates on +80V and +12V supplies, supporting pixel clock frequencies up to 100 MHz. It features 7.5 ns rise and fall times, stability with capacitive loads up to 20 pF, and is housed in a 9-lead TO-220 package.
Feature Summary
- Integrates three high input impedance, wide band amplifiers for direct RGB cathode driving
- Internally set gain of -14 per channel
- Stable operation with capacitive loads up to 20 pF and inductive peaking networks
- Compatible with standard LM243X family pinout for simplified PCB layout
Applications
- Color monitors with 1024 x 768 resolution at 85 Hz refresh rates
- Displays utilizing video blanking techniques
- Systems requiring pixel clock frequencies up to 100 MHz
Procurement Notes
Verify the component matches the specific LM2437T/NOPB designation from Texas Instruments or authorized distributors. Confirm the datasheet revision SNOS418A aligns with your design requirements. Ensure the TO-220 package variant corresponds to the staggered lead style specified for this part number. Cross-reference ordering suffixes to confirm compliance with current environmental standards.
Selection Notes
Select this component for high-resolution CRT driver circuits requiring fast transient response. The fixed internal gain simplifies external resistor networks. Consider thermal management capabilities when designing for high-frequency operation. Verify compatibility with preceding video preamplifiers like the LM1279 for complete signal chain integration.
Part Context
The LM2437 belongs to the LM243X family of monolithic CRT drivers. It is specifically engineered for XGA resolution markets. The device replaces discrete amplifier solutions by integrating three channels into a single power package. This consolidation reduces board space and improves signal integrity in video processing paths.
Replacement Considerations
Consult official documentation for compatible members of the LM243X family. Verify pinout compatibility before substituting other variants within the series.
