摘　　要：设计了一个可在线改变运行频率的步进电机驱动器脉冲源.电路主要用了两片MAX5160,一片555时基电路.MAX5160是32级可调的数字电位器,制成的脉冲源频率从288 Hz-14.4 kHz32级可调.A multivibrator type oscillator for the step motor driver has been designed. Two digital potentiometers （MAXS160） are used in the circuit. MAXS160 has 32 tap points that are accessible to the wiper. Therefore the oscillator is adjustable online to output 32 pulses that have different frequency. The pulse frequency can be changed from 288Hz to 14.4 kHz.
