The OPA521 is a power line communications (PLC) line driver that meets the conducted emissions requirements in CENELEC bands A, B, C and D and ARIB STD-T84 and FCC Part 15. This device is designed for driving high-current, low-impedance lines up to 1.9 A into reactive loads. With optimized internal protection structures, the OPA521 requires minimal external protection components that enable a minimal system solution cost.
