I need to amplify a sine wave signal of about 1mV to collect its frequency. I use AD620+active bandpass filter+OP07 amplification for signal acquisition. At present, after the second-level active filt
As shown
The input Uin of the op amp is obtained from the -380VDC bus through resistor voltage division to obtain -3.5VDC
Is the op amp in the figure a simple inverting 1:1 amplifier circuit, or is it
