Device Overview

Summary

The Le87536 is a dual channel differential amplifier designed to drive full rate ADSL2+ signals with very low power dissipation. The Le87536 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. The drivers achieve better than -75 dB THD while driving a 1MHz, 16Vp-p signal into a 60Ohm load. The amplifiers are enabled by forcing the ENAB/ENCD pins to ground. Leaving the ENAB/ENCD pins floating or forcing them high will disable the two amplifiers. The ENAB and ENCD pins are pulled up to an internal 2.5V through on-chip 50kOhm resistors. Le87536 device is one of the most cost-effective and high performance line drivers for ADSL2+ applications.
