EL2480CN

Overview

The EL2480CN is a quad current-feedback operational amplifier manufactured by Elantec Semiconductor. It provides a -3dB bandwidth of 250MHz at a gain of +1 while consuming only 3mA of supply current per amplifier. The device operates with dual supplies ranging from ±1.5V to ±6V or single supplies from +3V to +12V. It can output 55mA while swinging to ±4V on ±5V supplies. Key specifications include a slew rate of 1200V/µs and differential gain/phase errors of 0.05% and 0.05° respectively into a 150Ω load.

Feature Summary

• Quad topology integrating four independent current-feedback amplifiers in a single package
• High-speed performance with 250MHz bandwidth and 1200V/µs slew rate
• Low power consumption with 3mA supply current per amplifier
• Flexible operation supporting both single and dual supply voltages down to ±1.5V

Applications

• HDSL amplifiers
• Video amplifiers
• Cable drivers
• RGB amplifiers
• Test equipment amplifiers

Procurement Notes

Verify the manufacturer source, as Elantec Semiconductor was acquired by Intersil, which was subsequently acquired by Renesas Electronics. Ensure the component datasheet aligns with the specific revision history of the EL2480 series. Confirm that the 'CN' suffix corresponds to the correct commercial temperature range and packaging configuration required for your design. Cross-reference pinouts with official documentation to avoid compatibility issues with legacy designs.

Selection Notes

Select this component when multiple high-speed channels are required within a compact footprint. The quad configuration offers space efficiency compared to using individual single or dual amplifiers. Consider the 250MHz bandwidth and low noise characteristics for signal integrity in video or data transmission applications. Evaluate the thermal dissipation requirements given the 55mA output capability and the specific package options available for surface mounting.

Part Context

The EL2480CN belongs to the EL2180/EL2280/EL2480 family of current-mode feedback amplifiers. This series is designed for applications requiring high speed and low power consumption. The quad variant specifically integrates four amplifiers, providing a cost-effective solution for multi-channel systems. The family shares common electrical characteristics, differing primarily in the number of integrated amplifiers and package styles such as SOT23 and LPP.
