xDSL Differential Line Driver

The ISL1558 is a quad operational amplifier designed for VDSL2 and ADSL2+ line driving in DMT based solutions. This device 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.

The ISL1558 is available in the thermally-enhanced 24 Ld QFN package and is specified for operation over the full -40°C to +85°C temperature range. The ISL1558 has control pins C enable/disable of the outputs. These controls allow for lowering the power to fit the performance/power ratio for the application.

The ISL1558 is ideal for VDSL2 and ADSL2+ central office line driving applications, including both 14.5dBm and 21dBm applications.
