ISL1556IUEZ

Special Purpose Amplifiers Overview

The ISL1556IUEZ is a dual operational amplifier designed as an xDSL differential line driver. It features a gain-bandwidth product of 250 MHz and a slew rate of 1.2 kV/us. The device operates on power supply voltages ranging from 4.5 V to 13.2 V, with a maximum rating of 12 V for specific configurations. It draws a typical operating current of 6 mA and exhibits an input offset voltage of 7.5 mV. The component is housed in a 10-pin HMSOP package with an exposed pad.

Special Purpose Amplifiers Feature Summary

• Dual operational amplifier architecture optimized for differential line driving applications
• High-speed performance suitable for DMT-based broadband solutions
• Low static current consumption for energy-efficient operation

Special Purpose Amplifiers Applications

• VDSL line driving
• ADSL line driving
• Power line communication systems

Special Purpose Amplifiers Procurement Notes

Verify the manufacturer designation, as Renesas Electronics acquired Intersil. Confirm the exact suffix (e.g., IUEZ) matches the required package type and temperature range. Check RoHS compliance status through official documentation. Ensure the source provides valid traceability for this discontinued or legacy part number.

Special Purpose Amplifiers Selection Notes

Select this component when designing circuits requiring high slew rates for DSL signal integrity. Compare against newer integrated transceivers if system complexity allows. Verify that the 10-HMSOP package fits the PCB layout constraints. Consider the 250 MHz bandwidth relative to the target data rates.

Special Purpose Amplifiers Part Context

This part belongs to the Intersil specialized amplifier family, now under Renesas Electronics. It serves as a discrete solution for line drivers before integration into single-chip DSL transceivers became prevalent. The device supports both ADSL and VDSL standards using discrete op-amp stages.
