EL4393CM

Overview

The EL4393CM is a triple wideband current feedback video amplifier manufactured by Elantec Semiconductor. It integrates three independent amplifiers optimized for high-speed video signal processing within a single SOIC-16 package. The device operates on dual power supplies ranging from ±4V to ±15V. Each channel features a disable function controlled by TTL/CMOS compatible logic signals, allowing for precise output control. The component provides an 80MHz -3dB bandwidth for gains between 1 and 10, with a slew rate of 900V/µs and a flat 10MHz bandwidth to 0.1dB.

Feature Summary

• Integrates three wideband current feedback amplifiers optimized for video performance
• Includes disable capability controlled by TTL/CMOS compatible logic signals
• Capable of driving 150Ω loads at standard video levels
• Operates on supply voltages as low as ±4V up to ±15V

Applications

• Video signal distribution systems
• High-speed analog video processing circuits
• Professional broadcast equipment requiring differential gain and phase accuracy

Procurement Notes

Verify the manufacturer designation matches Elantec Semiconductor or its successor entity, Intersil/Renesas, depending on production date. Confirm the package type is SOIC-16 (PDSO16) and that the suffix 'CM' indicates the specific commercial temperature range and packaging variant. Ensure datasheet revisions align with the required specifications for bandwidth and disable logic compatibility before integration.

Selection Notes

Select this component when multiple independent video channels are required in a compact form factor. The current feedback architecture supports high slew rates suitable for fast video transitions. Consider the ±4V to ±15V supply range for system power design. The integrated disable feature simplifies control logic compared to discrete solutions. Verify thermal requirements for the SOIC-16 package in the final enclosure design.

Part Context

Elantec Semiconductor specialized in high-performance analog and mixed-signal integrated circuits before being acquired by Intersil Corporation in 2016. Intersil was subsequently acquired by Renesas Electronics Corporation. The EL4393 series represents the company's expertise in video amplifier technology, utilizing current feedback architectures to achieve wide bandwidths and high slew rates essential for professional video applications.

Replacement Considerations

Public confirmed substitute part numbers include EL4393, EL4393C, and EL4393CN. These variants share the same functional description as Triple 80 MHz Video Amplifiers with Disable. Verify pinout compatibility and electrical parameter tolerances against the original design requirements before substitution.
