The ISL1557 is a dual operaTIonal amplifier designed forVDSL2 and ADSL line driving in DMT based soluTIons. Thisdevice 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.The ISL1557 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 ISL1557 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 ISL1557 is ideal for ADSL2+, SDSL, HDSL2 and VDSLline driving applications, including both 14.5dBm and 21dBmapplications.
