摘要
电压波形函数发生器在工业设备领域应用很广泛。如能用较少的成本设计出稳定度和精度都很高的波形产生电路,无疑会增加它的应用价值。在设计中应用高频波形发生器MAX038芯片,辅以程控电压放大芯片PGA202和由集成运放ADOP37组成的电压跟随驱动电路,实现了一个低成本、高精度、输出频率连续可调,具有较强驱动能力的电压波形函数发生器。
Waveform generator is widely used in the field of industry instruments. If a low cost waveform generator provides excellent stabilization and precision, it has more and more values in use. In this design, IC chip MAX038 is adopted, a digitally controlled programmablegain instrumentation amplifier PGA202 and driving IC ADOP37 can produce a generator which can provide a low cost,precise,adjusted continuously and driving powerful frequency waveform.
