The ISL1535A is a very low power dual channel

differentiated amplifier designed for central office line driving

for DMT ADSL2+ solutions. This device features a high drive

capability of 600mA while consuming 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 ISL1535A is available in a 28 Ld

HTSSOP package and a 24 Ld QFN package. This device is

specified for operation over the full -40°C to +85°C

temperature range.

The ISL1535A 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 ISL1535A maintains excellent distortion

and load driving capabilities even in the lowest power

settings. The ISL1535A has extended bandwidth, low THD

and high slew rate for ADSL2+ applications.
