Le87251 - Zarlink Semiconductor

Le87251 Worldwide ADSL2+ Dual Channel Line Driver

The Le87251 is a dual channel differential amplifier designed to drive full rate ADSL2+ signals with very low power dissipation. The Le87251 contains two pairs of wide band amplifiers designed with Zarlink’s HV30 Bipolar SOI process for low power consumption in DSL systems. The amplifiers have an internal fixed gain, which helps to eliminate external feedbac.
