WebFigure 1 shows the open-loop gain and phase vs. frequency for the ADA4610, a popular precision op amp. The plot shows that the op amp gain at low frequency is greater than 30,000 (90 dB), rolling off at 20 dB per decade, and reaching unity (0 dB) at about 10 MHz—known as the unity-gain crossover frequency. Web1 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.
