Web17 de jan. de 2024 · What I am after is an operational understanding of how an op-amp integrator works. I know how a simple RC circuit can integrate, what I don't understand is how the feedback loop in an op-amp configuration helps. I understand how feedback works in a noninverting amplifier. Web7 de fev. de 2024 · However few op amps will work with supplies much below 5V. The MCP6042 is a micropower op amp intended for very low frequency applications - hence the GBw of only 14kHz - its NOT a misprint! Recommendations. For a single supply driven from your Arduino's 5V or 3.3V supply, WebBecause op-amps have extremely high input impedance, there is virtually no current flow into the inverting input (−). Accordingly, I 1 flows through point A and R 2; this means that I 1 and I 2 are virtually equal. Then, by Ohm's Law, we have Vout = −I 1 × R 2, where I 1 is negative because I 2 flows from point A, where the voltage is 0. Looking at this in … エコノミストオンライン
