概要
説明
Support is limited to customers who have already adopted these products.
The ISL1556 is a dual operational amplifier designed for VDSL and ADSL line driving in DMT based solutions. This device features a high drive capability of 350mA while consuming only 4. 5mA 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 ISL1556 is available in the thermally-enhanced 16 Ld QFN package and is specified for operation over the full -40°C to +85°C temperature range. The ISL1556 has control pins C0 and 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 ISL1556 is ideal for ADSL2+, SDSL, HDSL2 and VDSL line driving applications, including both 14. 5dBm and 17. 5dBm applications.
