The EL1527 is a very low power dual channel differentiated amplifier designed for central office and customer premise line driving for DMT ADSL solutions. This device 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 EL1527 has two control pins, C0 and C1, per channel. With the selection of C0 and C1, the device can be set into full-IS power, 3/4-IS power, 1/2-IS power, and power-down disable modes. The EL1527 maintains excellent distortion and load driving capabilities even in the lowest power settings. The EL1527 is available in the thermally-enhanced 28 Ld HTSSOP package. This device is specified for operation over the full -40°C to +85°C temperature range.
The EL1527 is a very low‑power dual‑channel differential amplifier designed for central‑office and customer‑premise line driving in DMT ADSL solutions. It provides up to 360 mA drive current at 16 Vpp on a +12 V supply, 40 Vpp differential output into 100 Ω, and typical distortion better than –75 dBc at 1 MHz into 50 Ω.
The device is supplied in a 28‑lead HTSSOP package, operates over –40 °C to +85 °C, and includes power‑down disable mode. It is RoHS‑compliant (Pb‑free) and requires careful ESD handling. Ordering information and pinout details are provided in the datasheet.
