The ISL1557A is a dual operational amplifier designed for VDSL2 and ADSL line driving in DMT based solutions. This device features a high drive capability of 750mA whileconsuming only 6mA of supply current per amplifier andoperating from a single 4.5V to 12V supply. The driverachieves a typical distortion of -80dBc, at 150kHz into a 25Ωload. ISL1557A is design with stronger output clamps toenhance protection against lightning transients.The ISL1557A is available in the thermally-enhanced16 Ld QFN and 10 Ld HMSOP package and is specified foroperation over the full -40°C to +85°C temperature range.The ISL1557A has control pins C0 and C1 for controlling thebias and enable/disable of the outputs. These controls allowfor lowering the power to fit the performance/power ratio forthe application.The ISL1557A is ideal for ADSL2+, SDSL, HDSL2 andVDSL line driving applications, including both 14.5dBm and 21dBm applications.
