Introduction

AI Translation

The ISL1557A is a dual operational amplifier designed for line driving in DMT ADSL2+ and VDSL solutions. It is a dual current mode feedback amplifier with low distortion that draws a moderately low supply current. It is built using proprietary Renesas complimentary bipolar process and is offered in industry standard pinouts. Due to the current feedback architecture, the ISL1557A closed-loop 3dB bandwidth is dependent on the value of the feedback resistor.
