应用电路: 低频锁相环波形函数发生器 The ICL8038 waveform generator is a monolithic integrated circuit capable of producing high accuracy sine, square,triangular, sawtooth and pulse waveforms with a minimum of external components. The frequency (or repetition rate) can be selected externally from 0.001Hz to more than 300kHz using either resistors or capacitors,
