Teachers, I would like to ask you, there is a peak value of more than 300mV on the 5V power supply, and the peak width is 200us. Will it affect the operation of the circuit?
I use 7815 7915 positive and negative power supplies to power AD620. I input a 20mV DC signal and amplify it 15 times. The signal should be 300mV DC. But now the waveform is a square wave with a frequ
