| Abstract: | PZT driving power is the key component in the application of the micro-displacement piezoelectric actuator. The PA85 is a bandwidth operational amplifier with the high voltage, high power MOSFET, which is supplied by the dual power. Its out- put current reaches up to 200mA and the output voltage can be up to ±215V. The design and simulation of the PA85 based driving power composite amplifier are elaborated in this paper. The amplifier＇s performances are analyzed through the simulation with a result of high precision, high resolution, well stability, low ripple wave and simple circuit structure. |
