The EL1511 is a medium power differential line driver ideal for ADSL, SDSL and HDSL2 line driving applications. The device features a high drive capability of 360mA while consuming only 7.5mA of supply current per amplifier and operating from a single 5V to 15V supply. This driver achieves a typical distortion of less than -85dBc, at 150kHz into a 25Ω load.
The EL1511 is a dual operational amplifier designed for line‑driving in DMT ADSL solutions. It delivers a high drive capability of 360 mA from a single 5 V to 15 V supply while consuming only a few milliamps per amplifier.
The device operates over a temperature range of –40 °C to +85 °C, offers selectable power modes via control pins, and is available in 16‑lead SOIC and 16‑lead QFN packages. It is RoHS‑compliant and intended for ADSL, SDSL, and HDSL2 applications as well as video distribution.
