Opamp with 90db gain

Web2 de nov. de 2024 · The maximum gain is the open loop gain. It depends on the opamp model, and can go anywhere from 60 dB to 120 dB voltage gain. The open-loop bandwidth is however very small. Another issue is that this gain is very variable between different parts of the same product number due to variations. Web21 de nov. de 2024 · Choose the type of op-amp, e.g., inverting, from the drop-down menu. Enter the values of input resistance (1 kΩ) and feedback resistance (10 kΩ). The op-amp calculator will display the voltage gain of the op-amp, e.g., 10. If you select non-inverting op-amp, the calculator will show 11.
