ISL1536

Dual Channel Central Office ADSL2+ Line Driver

OVERVIEW

The ISL1536 is a very low power dual channel differential amplifier designed for central office line driving for DMT ADSL2+. This device features a high drive capability of 400mA while consuming only 4mA of supply current per amplifier from ±12V supplies. It integrates gain and bias resistors while maintaining high slew rate and low distortion.
