I have the following circuit (a band-pass filter) and I cannot understand what's the difference of a 1000kΩ resistance to a 1MΩ as seen here:
With R223 = 1000k, my circuit outputs the expected theoretical results (for input signal of 32kHz at amplitude of 500mV, it retains indeed 500mV almost) , but when I replace it with a 1M resistance it outputs 74mV amplitude instead, which is totally illogical! Maybe I have missed something obvious here? But aren't those two resistors exactly equal? Isn't 1000k = 1M? And the weirdest thing is that the real circuit (not simulation) also outputs the "illogical" result of 74mV!
