Hi all,
I made an amplifier circuit using LM675, the schematic diagram is
When the circuit is directly connected to oscilloscope. Signal is heavily distorted by harmonics. The input signal is 5Hz and 2Hz sin wave, Vcc=27V, Vee=0, but the output waveform is distorted like spike. More harmonics component, more distortion. What I want to know is that what is the cause of harmonic distortion in low frequency, and how to remove this distortion? Thanks a lot!!!!!
