The EL1507 is a medium power differential line driver from Bel Communications. It features a high drive capability of 400mA while consuming only 7.5mA of supply current per amplifier from ±12V supplies. This driver achieves a typical distortion of less than -75dBc, at 1MHz into a 50Ω load. The EL1507 is available in the thermally- enhanced 16 Ld SO package, as well as a 16 Ld QFN package. Both are specified for operation over the full -40°C to +85°C temperature range. The EL1507 has two control pins, C0 and C1. With the selection of C0 and C1, the device can be set into full-IS power, ¾-IS power, ½-IS power, and power down disable modes. The EL1507 maintains excellent distortion and load driving capabilities even in the lowest power settings.
The EL1507 is a very low‑power dual operational amplifier designed for central‑office and customer‑premise line driving in DMT ADSL solutions. It offers high drive capability (up to 360 mA) while consuming only a few milliamps from a +12 V supply and maintains low distortion across a wide frequency range.
Key specifications include a 40 Vp‑p differential output into 100 Ω, typical distortion below –75 dBc at 1 MHz into 50 Ω, and operation over –40 °C to +85 °C. The device is offered in 16‑lead SOIC and 16‑lead QFN packages, both RoHS‑compliant and suitable for Pb‑free soldering processes.
