ISL1571
Power Line Communication (PLC)
FN6387
Rev 1.00
September 3, 2009
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 BIAS0 and BIAS1 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.

• Supply range
- For ISL1571IUEZ 4.5V to 12V
- For ISL1571IRZ ±2.25V to ±6V, 4.5V to 12V
• 250MHz bandwidth
• Thermal shutdown
• Pb-free (RoHS compliant)
Applications
• Homeplug 1.0
• Homeplug AV
• UPA digital home standard

NOTE: These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100%
matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations).
Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J
STD-020.
