ISL1571IRZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL1571IRZ is a dual operational amplifier designed for Power Line Communication (PLC) line driving in OFDM and SSC solutions. It features a 250 MHz bandwidth, 1200 V/µs slew rate, and 6 nV/√Hz input noise density. The device operates from a single 4.5V to 12V supply or dual ±2.25V to ±6V supplies, consuming 6 mA per amplifier. It offers 1 A output current capability and includes thermal shutdown protection. Available in a 16-lead QFN package, it supports Homeplug 1.0, Homeplug AV, and UPA standards.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package type upon ordering, as the ISL1571 series includes both 10-lead HMSOP and 16-lead QFN variants. Confirm that the suffix 'IRZ' corresponds to the QFN package and tape/reel packaging format. Ensure compatibility with the required supply voltage range of 4.5V to 12V for single-supply applications or ±2.25V to ±6V for dual-supply configurations.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for high-speed PLC applications requiring significant output drive current while maintaining low power consumption. The device is suitable for designs adhering to Homeplug 1.0, Homeplug AV, and UPA standards. Consider the 16-lead QFN package for thermal performance and space constraints. Verify that the 250 MHz bandwidth meets the signal integrity requirements of the target communication protocol.
