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 25Ω 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 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 ISL1572 is a dual operational amplifier designed for Power Line Communication (PLC) line driving in OFDM and SSC solutions. It operates from a single 4.5 V to 12 V supply and offers high drive capability while consuming only 6 mA per amplifier.
