The ISL1558 is an Intersil quad operational amplifier designed for VDSL2 and ADSL2+ line driving in DMT based solutions. It features a high drive capability of 750mA while consuming only 6mA of supply current per amplifier at low bias and operating from a single 4.5V to 12V supply. The driver achieves a typical distortion of -80dBc, at 200kHz into a 50Ω differential load.
