The EL1519 is a dual operational amplifier 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 EL1519 is available in the industry standard 8 Ld SO. This device is optimized to use low feedback resistor values to minimize noise in ADSL systems. The EL1519 is ideal for ADSL, SDSL, HDSL2 and VDSL line driving applications.
The EL1519 is a dual operational amplifier designed for customer‑premise line driving in DMT ADSL solutions. It offers a high drive capability of up to 250 mA per amplifier, low quiescent current, and typical distortion below –85 dBc at 150 kHz. The device is supplied in an 8‑lead SO package and is RoHS‑compliant.
