Dual Channel Central Office ADSL2+ Line
Driver

The ISL1535 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 5.2mA 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 ISL1535 is available in 28 Ld HTSSOP
package. This device is specified for operation over the full

-40°C to +85°C temperature range.
The ISL1535 has two control pins, C

With the selection of C

disable modes. The ISL1535 maintains excellent distortion
and load driving capabilities even in the lowest power
settings. The ISL1535 has extended bandwidth, low THD
and high slew rate for ADSL2+ applications.
