In this paper, the design of high power intelligent signal source for drivable capactive load taking AT89C55 as core was described. The new methods of using monolithic processor in its software and hardware design such as the principle bloack diagram, the chart of mainstream of procedure were introduced. The production of signal source, power amplifier of drivable capacitive load etc. were analyzed. So, by introducing monolithic processor into power amplifier technology, the integral design reliability was upgraded greatly. Through communication between computer and monolithic processor, the effective remote intelligent control may be realized.
