Device Overview

Summary

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 Microchip's HV30 Bipolar SOI process for low power consumption in DSL systems. The amplifiers have an internal fixed gain, which helps to eliminate external feedback and gain setting resistors.
