EL1517ILZ

Overview

The EL1517ILZ is a dual operational amplifier designed for xDSL differential line driving in DMT-based solutions. It provides a high drive capability of 250mA while consuming only 7mA of supply current per amplifier, operating from a single 5V to 12V supply. The device achieves typical distortion levels of -80dBc at 150kHz into a 25Ω load and features a 200MHz bandwidth. Available in the industry-standard 16 Ld QFN package, it includes control pins C0 and C1 for managing bias and output enable/disable states. All variants are specified for operation over the full -40°C to +85°C temperature range.

Feature Summary

• Dual operational amplifier architecture optimized for xDSL differential line driving applications
• High drive capability delivering up to 250mA with low quiescent current consumption
• Integrated control pins for precise management of bias and output enable/disable states
• Low distortion performance across multiple frequency bands including 150kHz and 16MHz

Applications

• VDSL line drivers
• ADSL full rate CPE line driving
• G.SHDSL and HDSL2 line drivers
• HomePlug networking drivers

Procurement Notes

Verify component authenticity through authorized channels as Intersil products are sold by description only. Confirm datasheet currency before implementation since specifications may be modified without notice. Ensure thermal pad connection to negative supply for proper heat dissipation in the QFN package. Validate RoHS compliance requirements against specific project standards.

Selection Notes

Select the EL1517ILZ when requiring a dual op-amp solution specifically tailored for xDSL line driving tasks. The 16 Ld QFN package offers thermal enhancement and dedicated control pins not present in the SOIC variant. Consider the 250mA drive capability and 200MHz bandwidth for high-frequency signal integrity requirements in broadband communication systems.

Part Context

The EL1517 series was originally manufactured by Intersil Corporation before its acquisition by Renesas Electronics. This component represents a specialized analog interface solution developed for digital subscriber line technologies. The product line focuses on providing efficient power-to-performance ratios for telecommunications infrastructure equipment.

Replacement Considerations

This component is classified as an obsolete product with no recommended replacement available. Designers must evaluate alternative components independently or consider redesigning the circuit board to accommodate newer generation amplifiers that meet similar electrical specifications.
