Description
The EL1517A is a dual operational amplifier designed for VDSL and ADSL line driving in DMT based solutions. 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 EL1517A 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 EL1517A is ideal for ADSL, SDSL, HDSL2 and VDSL line driving applications. The "A" suffix is used only for package leadframe distinction between EL1517. All performance graphs in this datasheet were generated for EL1517IS and EL1517IL. There is no significant electrical difference between EL1517AIYE and the performance curves for EL1517IL.
The EL1517A can only be used for single supply operation. Use EL1517IL or EL1517IS for dual supply applications.
Applications
- VDSL line drivers
- ADSL full rate CPE line driving
- G.SHDSL, HDSL2 line drivers
- HomePlug networking drivers
