The Output Power Amplifier meets the requirements specified by the EIA-600 (CEBus Standard) for output voltage levels into typical and low impedance power line loads and incorporates over-temperature protection for improved system reliability. The IC replaces approximately 30 of the discrete components normally used in support of PL transceivers and reduces required printed circuit board area by up to 50%.
