EL2480CS

Overview

The EL2480CS is a quad current-feedback operational amplifier manufactured by Renesas Electronics, formerly Elantec. It delivers a -3dB bandwidth of 250 MHz at a gain of +1 and a slew rate of 1200 V/µs while consuming only 3 mA of supply current per channel. The device supports dual supplies from ±1.5V to ±6V or single supplies from +3V to +12V. It features an output drive current of 55 mA and operates within a temperature range of -40°C to 85°C. The component is housed in a 14-SOIC package.

Feature Summary

• Quad current-feedback topology providing high-speed signal processing with low power consumption
• Wide supply voltage operation supporting both single and dual power configurations
• High slew rate and bandwidth suitable for demanding video and RF applications

Applications

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

Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm availability through authorized distributors or secondary markets. Ensure replacement strategies are defined as manufacturing may have ceased. Validate pin compatibility if substituting with similar devices from other manufacturers.

Selection Notes

Select this component for designs requiring high bandwidth with minimal power draw. Consider the 14-SOIC package constraints for PCB layout. Evaluate thermal performance given the quad configuration. Verify that the 55 mA output current meets load requirements without external buffering.

Part Context

This part belongs to the EL2480 family of current-feedback amplifiers. It shares specifications with the EL2480C variant but differs in packaging. The series includes single (EL2180) and dual (EL2280) versions. These amplifiers are designed for low-voltage, low-power applications requiring fast transient response.

Replacement Considerations

Public confirmed substitutes include OPA4684ID and OPA4684IDR from Texas Instruments.
