EL2045CS

Overview

The EL2045CS is a high-speed operational amplifier manufactured by Elantec, later integrated into the Intersil and Renesas product portfolios. It features a gain-bandwidth product of 100 MHz and operates with a supply voltage range of ±2 V to ±18 V. The device is housed in an 8-lead SOIC package (CS suffix) and is rated for industrial temperature operation from -40°C to +85°C. It is unity-gain stable and designed for low power consumption applications requiring fast signal processing.

Feature Summary

• High-speed performance with 100 MHz gain-bandwidth product
• Unity-gain stability for versatile circuit configurations
• Low power consumption suitable for battery-operated systems
• Industrial temperature range capability

Applications

• Video signal processing circuits
• High-speed data acquisition systems
• Active filtering applications
• Buffer amplifiers in communication equipment

Procurement Notes

Verify current availability status as this component may be subject to limited supply or end-of-life notifications from Renesas/Intersil. Confirm that the specific suffix 'CS' matches the required 8-lead SOIC package variant. Check for official obsolescence notices or alternate manufacturing site changes before finalizing procurement plans.

Selection Notes

Select this component when a 100 MHz bandwidth and unity-gain stability are required in a small surface-mount package. Ensure the application voltage stays within the ±2 V to ±18 V range. Consider thermal management if operating near the upper temperature limits. Verify pin compatibility with existing PCB layouts designed for standard SOIC-8 footprints.

Part Context

The EL2045 series belongs to a family of low-power, high-speed operational amplifiers originally developed by Elantec Semiconductor. Following corporate acquisitions, the product line was transferred to Intersil and subsequently to Renesas Electronics. This specific part represents a single-channel variant optimized for general-purpose high-frequency analog signal conditioning tasks.

Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Cross-reference specifications such as bandwidth, slew rate, and package dimensions with potential alternatives to ensure functional equivalence in high-speed designs.
