The EL1517B is a dual operational amplifier designed for VDSL and ADSL line driving in DMT based solutions. EL1517B includes internal protection for high ruggedness against lightning related transients. This device features a high drive capability of 250mA while consuming only 7mA of supply current per amplifier and operating from a single 5V to 12V supply. This driver achieves a typical distortion of 80dBc, at 150kHz into a 25Ω load. The EL1517B is available in a 10 Ld HMSOP package and is specified for operation over the full -40°C to +85°C temperature range. The device 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 EL1517B is ideal for ADSL, SDSL, HDSL2 and VDSL line driving applications. All performance graphs in this datasheet were generated for EL1517BIS and EL1517BIL. There is no significant electrical difference between EL1517BIYE and the performance curves for EL1517BIL.

The EL1517B can only be used for single supply operation. Use EL1517BIL or EL1517BIS for dual supply applications.
