EL1537B

The EL1537B is a very low power dual channel differentiated amplifier designed for central office 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 50 load. The EL1537B 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 EL1537B 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 EL1537B maintains excellent distortion and load driving capabilities even in the lowest power settings. The EL1537B has extended bandwidth and improved THD and slew rate for ADSL2+ and VDSL applications.
