ISL1557A
12V xDSL Differential Line Driver with
Enhanced Output Protection
The ISL1557A is a dual operational amplifier designed for
VDSL2 and ADSL line driving in DMT based solutions. This
device features a high drive capability of 750mA while
consuming only 6mA of supply current per amplifier and
operating from a single 4.5V to 12V supply. The driver
achieves a typical distortion of -80dBc, at 150kHz into a 25
Ω
load. ISL1557A is design with stronger output clamps to
enhance protection against lightning transients.
The ISL1557A is available in the thermally-enhanced
16 Ld QFN and 10 Ld HMSOP package and is specified for
operation over the full -40°C to +85°C temperature range.
The ISL1557A has control pins C0 and C1 for controlling the
bias and enable/disable of the outputs. These controls allow
for lowering the power to fit the performance/power ratio for
the application.
The ISL1557A is ideal for ADSL2+, SDSL, HDSL2 and
VDSL line driving applications, including both 14.5dBm and
21dBm applications.
