Dual Channel Central Office ADSL2+ Line Driver
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 50Ω 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.
