DATASHEET
ISL1571
Power Line Communication (PLC)
The ISL1571 is a dual operational amplifier designed for
PLC line driving in OFDM and SSC 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
load.
The ISL1571 is available in the thermally-enhanced
16 Ld QFN or 10 Ld HMSOP package and is specified for
operation over the full -40°C to +85°C temperature range. The
ISL1571 has control pins BIAS
0
and BIAS
1
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 ISL1571 is ideal for line driving applications following
the Homeplug 1.0, Homeplug AV and UPA standard based
PLC.
