描述 Description

The ISL1571 is a dual operational amplifier designed for PLC line driving in Orthogonal Frequency-Division Multiplexing (OFDM) and Spread Spectrum Communication (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 ISL1571 is available in the thermally-enhanced 16 Ld QFN or 10 Ld HMSOP package and is specified for operation across 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.
