EL5120IYE

Overview

The EL5120IYE is a single-channel, low-power, high-voltage operational amplifier manufactured by Intersil (now Renesas). It features rail-to-rail input and output capabilities, making it suitable for single-supply applications. Key electrical specifications include an 8MHz gain-bandwidth product, a slew rate of 10V/µs, and an operating supply current of 500µA. The device supports supply voltages ranging from 5V to higher limits defined by its high-voltage classification, with an output current capability of 30mA per channel.

Feature Summary

• Rail-to-rail input and output operation for maximum dynamic range
• Low power consumption with 500µA operating supply current
• High voltage capability suitable for diverse signal conditioning tasks

Applications

• Single-supply signal processing circuits
• Portable battery-powered instrumentation
• Industrial sensor interface stages

Procurement Notes

Verify the manufacturer status as Intersil has been acquired by Renesas Electronics Corporation. Confirm that the specific suffix 'IYE' corresponds to the industrial temperature range and 8-HMSOP package variant. Ensure RoHS compliance requirements are met, as some sources indicate this specific part number may not be compliant. Cross-reference the datasheet revision date to ensure compatibility with current design standards.

Selection Notes

Select the EL5120IYE when a single amplifier with rail-to-rail performance is required in a compact 8-HMSOP package. Compare against the EL5220 if dual channels are needed or the EL5420 for quad configurations within the same family. Consider the 8MHz bandwidth and 10V/µs slew rate for moderate-speed applications. Verify supply voltage constraints and thermal dissipation requirements for the specific PCB layout.

Part Context

The EL5120 belongs to the EL51xx/EL52xx/EL54xx family of low-power, high-voltage, rail-to-rail amplifiers. This series is designed to provide flexibility across different channel counts while maintaining consistent electrical characteristics. The EL5120 specifically offers a single amplifier configuration, distinguishing it from the dual-channel EL5220 and quad-channel EL5420 variants.

Replacement Considerations

Direct substitutes within the same family include the EL5220 for dual-channel needs and EL5420 for quad-channel needs. Check for updated Renesas part numbers as Intersil products transitioned to the Renesas portfolio. Ensure pinout compatibility and electrical parameter equivalence before substitution.
