EL1509CS

Overview

The EL1509CS is a dual operational amplifier designed for customer premise equipment line driving in DMT ADSL solutions. It features high drive capability of 250mA while consuming only 7.1mA of supply current per amplifier and operating from a single 5V to 12V supply. This driver achieves a typical distortion of less than -85dBc, at 150kHz into a 25Ω load. The device is available in the industry standard 8 Ld SOIC as well as the thermally-enhanced 8 Ld DFN package. Both are specified for operation over the full -40°C to +85°C temperature range.

Feature Summary

• Drives up to 250mA from a +12V supply
• Provides 20VP-P differential output drive into 100Ω
• Achieves -85dBc typical driver output distortion at full output at 150kHz
• Low quiescent current of 7.5mA per amplifier

Applications

• ADSL G.lite CO line driving
• ADSL full rate CPE line driving
• G.SHDSL, HDSL2 line driver
• Video distribution amplifier
• Video twisted-pair line driver

Procurement Notes

Verify the specific suffix CS against official Renesas or Intersil documentation to confirm package type and lead-free status. Ensure compatibility with existing PCB footprints for either SOIC or DFN configurations. Confirm that the component meets RoHS compliance requirements for the target market. Check for any obsolescence notices or last-time-buy notifications from authorized distributors before finalizing procurement plans.

Selection Notes

Select this component for applications requiring medium power differential line driving in ADSL and SHDSL environments. Consider the thermal performance of the DFN package if space constraints exist. Evaluate the 250mA drive capability against the specific line impedance requirements. Verify that the 5V to 12V single supply range aligns with the system power architecture.

Part Context

The EL1509 series includes variants such as EL1509CL and EL1509C. These devices are manufactured by Intersil Corporation and Renesas Technology Corp. They serve as medium power differential line drivers. The family is designed for robust performance in telecommunications line driving applications. The EL1509CS represents a specific configuration within this product line.

Replacement Considerations

Cross-reference with EL1509CL for potential pin-compatible alternatives. Verify electrical specifications match exactly before substitution. Consult manufacturer datasheets for any functional differences between variants.
