Description

General part information

ISL1557A Series

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 while consuming only 6mA of supply current per amplifier and operating from a single 4. 5V to 12V supply. The driver achieves a typical distortion of -80dBc at 150kHz into a 25Ω load. The ISL1557A is designed with stronger output clamps to enhance protection against lightning transients. The ISL1557A is available in the thermally-enhanced 16 Ld QFN and 10 Ld HMSOP package and is specified for operation over the full -40°C to +85°C temperature range. The ISL1557A has two control pins (C0and C1) for controlling the bias and enable/disable of the outputs. These controls allow for lowering the power to fit the performance/power ratio for the application. The ISL1557A is ideal for ADSL2+, SDSL, HDSL2, and VDSL line driving applications, including both 14. 5dBm and 21dBm applications.
