ISL1571 is a dual operational amplifier designed for PLC line driving in OFDM and SSC based solutions. It 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 25Ω 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 is a dual operational amplifier designed for power‑line communication (PLC) line‑driving applications such as HomePlug and UPA standards. It operates from a single 4.5 V to 12 V supply and delivers up to 750 mA drive current while consuming only 6 mA per amplifier.
Key features include 21 dBm output power, low‑noise floor, typical distortion of –80 dBc at 10 MHz, 250 MHz bandwidth, thermal shutdown, and RoHS‑compliant Pb‑free packaging. The device is offered in 16‑lead QFN and 10‑lead HMSOP packages and is rated for –40 °C to +85 °C operation.
