ISL1556IRZ

Special Purpose Amplifiers Overview

The ISL1556IRZ is a specialized differential line driver and receiver designed for xDSL applications. Manufactured by Intersil, now part of Renesas Electronics, this component operates within a single-supply voltage range and utilizes a 16-lead QFN (4x4 mm) package with an exposed pad for thermal management. It integrates both transmit and receive functions on a single chip to facilitate full-duplex communication over copper lines.

Special Purpose Amplifiers Feature Summary

• Integrates differential line driver and receiver functionality for compact system design
