EL5211IYE

Overview

The EL5211IYE is a high-speed, rail-to-rail input-output operational amplifier manufactured by Intersil. It features a bandwidth of 60MHz and a slew rate of 35V/µs, enabling rapid signal processing in demanding applications. The device operates on a single supply voltage ranging from 2.7V to 5.5V or dual supplies up to ±2.75V. It draws a quiescent current of 4.5mA per channel and maintains stability with capacitive loads up to 100pF. Packaged in an 8-lead SOIC surface-mount format, it supports extended industrial temperature ranges.

Feature Summary

• Rail-to-rail input and output capability for maximum dynamic range
• High slew rate of 35V/µs for fast transient response
• Unity-gain stable design simplifies circuit implementation
• Low power consumption suitable for battery-operated systems

Applications

• Video buffering and signal conditioning
• Portable instrumentation requiring wide dynamic range
• Active filtering in communication systems
• Data acquisition front-end stages

Procurement Notes

Verify the suffix 'IYE' confirms the industrial temperature grade and SOIC-8 package configuration against the official Intersil datasheet. Ensure compatibility with the specified 2.7V to 5.5V supply range. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the manufacturer part number to avoid confusion with similar legacy variants.

Selection Notes

Select this component when both input and output voltage swings must approach the supply rails within a single-supply architecture. It is appropriate for applications requiring moderate bandwidth without the complexity of external compensation networks. Consider the 4.5mA quiescent current draw against system power budgets. Verify that the load capacitance does not exceed 100pF to maintain stability without additional series isolation resistors.

Part Context

This device belongs to the EL5211 family of high-speed operational amplifiers designed for video and general-purpose analog signal processing. Intersil, now part of Renesas Electronics, produced this series to address the need for precision amplifiers in compact, low-voltage environments. The family emphasizes ease of use through unity-gain stability and robust performance across varying load conditions.

Replacement Considerations

Consult official substitution guides for equivalents such as the EL5211IZ or other rail-to-rail op-amps from Renesas. Verify pinout compatibility and electrical parameter overlaps before replacing. Note that package variations may require PCB layout adjustments.
