ISL1572
Power Line Communication (PLC)
The ISL1572 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 ISL1572 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 ISL1572 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.
