The EL1537A is a very low power dual channel differentiated amplifier designed for central office line driving for DMT ADSL solutions. The EL1537A has a higher output swing specification for driving 30Ω loads as compared to the EL1537. 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 EL1537A 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 EL1537A 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 EL1537A maintains excellent distortion and load driving capabilities even in the lowest power settings. The EL1537A has extended bandwidth and improved THD and slew rate for ADSL2+ and VDSL applications.
