EL2186CN

Overview

The EL2186CN is a quad current-feedback operational amplifier from the EL2180/EL2186 family, designed for high-speed applications with power efficiency. It achieves a -3dB bandwidth of 250MHz while consuming 3mA of supply current per amplifier. The device operates on dual supplies ranging from ±1.5V to ±6V or single supplies from +3V to +12V. It features industry-standard pinouts in PDIP and SO packages, making it suitable for space-constrained designs requiring multiple channels.

Feature Summary

• Quad topology providing four independent amplifiers in a single package
• High-speed performance with 250MHz bandwidth for demanding signal processing
• Low power consumption relative to speed, drawing 3mA per amplifier
• Flexible supply voltage operation supporting both single and dual rail configurations

Applications

• High-speed video buffering and distribution
• Test and measurement equipment signal conditioning
• Multi-channel data acquisition systems
• Broadband communication interfaces

Procurement Notes

Verify the manufacturer source, as Elantec assets were acquired by Renesas. Confirm the specific suffix 'CN' corresponds to the ceramic DIP package variant in official documentation. Ensure compatibility with existing board layouts referencing standard quad op-amp footprints. Check for updated datasheets under the Intersil/Renesas naming convention if sourcing from modern distributors.

Selection Notes

Select this component when multiple high-bandwidth channels are required without excessive power draw. Compare against the EL2170 series if lower bandwidth (70MHz) and even lower current (1mA) suffice. Consider the EL2186CS surface-mount version if PCB real estate is limited. Verify that the 250MHz bandwidth aligns with the application's frequency requirements to avoid over-specifying cost.

Part Context

The EL2186CN belongs to the EL2180/EL2186 family of current-mode feedback amplifiers developed by Elantec Semiconductor, later integrated into Intersil and subsequently Renesas. This family bridges the gap between low-power general-purpose amplifiers and ultra-high-speed devices. The quad configuration offers a compact solution for multi-channel systems where board space and power budget are critical constraints.

Replacement Considerations

Direct substitutes include other quad current-feedback amplifiers with similar 250MHz bandwidth and 3mA current draw. Verify pinout compatibility with standard quad op-amp packages. Cross-reference with EL2186CS for surface-mount equivalents. Ensure replacement parts maintain the same supply voltage range and output drive capabilities.
