Intersil EL1537A Dual Channel ADSL2+ Line Driver Datasheet
The EL1537A is a very low power dual‑channel differentiated amplifier designed for central‑office line driving in DMT ADSL solutions. It offers a high drive capability of 400 mA while consuming only 7.5 mA per amplifier from a +12 V supply and provides typical distortion of less than –75 dBc at 1 MHz into a 50 Ω load.
The device includes two control pins per channel, allowing full‑Ig, 3/4‑Ig, 1/2‑Ig, and power‑down disable modes. It maintains excellent distortion and load‑driving performance even at the lowest power settings and is specified for operation over –40 °C to +85 °C.
