Other Parts Discussed in Thread: TLV9061
Hi Team,
We want to amplify the small PWM signal, the circuit is shown in the picture. The simulated result shows that the output voltage is not always the PWM signal, it seems that the inverting input of LM324 is not equal to the non-inverting input.
However, if LM324 is changed to TLV9061, the output is PWM signal as expected, could you please help advise the reason why LM324 output voltage is not always PWM? Thanks!
Best Regards!
