Telecom datasheet and documents for ISL1557IUEZ

ISL1557IUEZ

Telecom Overview

The ISL1557IUEZ is a dual operational amplifier designed for VDSL2 and ADSL line driving in DMT-based solutions. It features a high drive capability of 750mA while consuming only 6mA of supply current per amplifier and operating from a single 4.5V to 12V supply. The driver achieves a typical distortion of -80dBc at 150kHz into a 25Ω load. The ISL1557A is available in the thermally-enhanced 16 Ld QFN and 10 Ld HMSOP package and is specified for operation across -40°C to +85°C (IRZ, IUEZ) temperature ranges.

Telecom Feature Summary

Designed with stronger output clamps to enhance protection against lightning transients
Features two control pins (C0 and C1) for controlling the bias and enable/disable of the outputs
Offers low quiescent current of 6mA per amplifier

Telecom Applications

VDSL2 line drivers
ADSL2+ CPE line driving
G.SHDSL and HDSL2 line drivers

Telecom Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature range. Confirm that the component meets RoHS compliance standards as indicated by the Pb-free designation. Ensure the thermal pad connection requirements are properly addressed during PCB layout to maintain optimal performance and reliability.

Telecom Selection Notes

Select this component for applications requiring high drive capability and low power consumption. Consider the 10 Ld HMSOP package for single-supply applications. Verify that the input common mode range is not exceeded when using single supply voltages. Ensure proper bypassing and layout practices are followed for optimum AC performance.

Telecom Part Context

The ISL1557IUEZ belongs to the ISL1557A family of dual operational amplifiers. This family is specifically engineered for xDSL differential line driving applications. The device utilizes a proprietary Renesas complimentary bipolar process for enhanced performance.
