LM2476TB/NOPB

Overview

The LM2476TB/NOPB is a video amplifier module from Texas Instruments designed for CRT driver applications. It integrates three independent video amplifiers with adjustable gain and bias clamps, alongside a dedicated CRT driver circuit for stable output. The device operates on a single supply voltage ranging from 60V to 85V. It is housed in a TO-247 package with formed leads, facilitating through-hole mounting for robust industrial or high-power video systems.

Feature Summary

• Integrates three independent video amplifiers with adjustable gain
• Includes integrated bias clamps for signal conditioning
• Features a dedicated CRT driver circuit for stable output performance

Applications

• CRT driver circuits
• Video amplifier modules
• Industrial video processing systems

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the TO-247 package variant matches your PCB footprint requirements. Ensure the input supply voltage remains within the 60V to 85V operational range during system design validation.

Selection Notes

Select this component when designing systems requiring multiple synchronized video channels driven by a single IC. The high supply voltage capability distinguishes it from standard low-voltage video op-amps. Consider the thermal dissipation characteristics of the TO-247 package for heat management in enclosed enclosures.

Part Context

This part belongs to the LM2476 series, specialized for analog video signal processing. Unlike general-purpose amplifiers, it is optimized for the specific timing and amplitude requirements of cathode ray tube displays. The NOPB suffix denotes a non-pb (lead-free) manufacturing process compliant with environmental directives.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing CRT driver designs before considering alternative vendors.
