Hello, we use opa1632 single-ended to differential, the two outputs (non-inverting output, inverting output) peak and peak are not equal [according to the data sheet, we believe that the output should be 180° phase difference, peak-to-peak waveform, if not, Thank you for correcting me! ! 】 In the case where the input peak-to-peak value is 2V, the difference between the two ends is from 20mV to 120mV. What may be caused by this? How to verify and modify
The following is the circuit diagram
Signal detection when the input is peak-to-peak 2V, frequency is 500Hz, and offset is zero
Yellow waveform is the input signal
Blue waveform is the inverting output
Purple waveform is the non-inverting output
