The EL1509 is a medium power differential line driver designed for customer premise line driving in DMT ADSL solutions. This device features a high drive capability of 250mA while consuming only 7.1mA of supply current per amplifier and operating from a single 5V to 12V supply. This driver achieves a typical distortion of less than -85dBc, at 150kHz into a 25Ω load. The EL1509 is available in the industry standard 8 Ld SOIC as well as the thermally-enhanced 8 Ld DFN package. Both are specified for operation over the full -40°C to +85°C temperature range. The EL1509 is ideal for ADSL, SDSL, HDSL2 and VDSL line driving applications.
The EL1509 is a dual current‑mode feedback operational amplifier designed for line‑driving in DMT ADSL solutions and other high‑speed data applications. It delivers up to 250 mA output current, low quiescent current, and typical distortion below –85 dBc at 150 kHz, making it suitable for ADSL, SDSL, HDSL2, VDSL and video distribution.
The device is offered in 8‑lead SOIC and 8‑lead DFN packages, operates from +2.5 V to +12 V, and is specified for –40 °C to +85 °C. The datasheet includes detailed electrical specifications, typical performance curves, and layout recommendations such as short lead lengths, solid ground planes and proper power‑supply bypassing.
