WebLTC6910-1 is programmable for eight gain magnitudes of 0, 1, 2, 5, 10, 20, 50, or 100 Volts/Volt—much like a classic oscilloscope amplifier plug-in or lab amplifier with a gain knob, but much smaller. WebThe operational amplifiers bandwidth is the frequency range over which the voltage gain of the amplifier is above 70.7% or -3dB (where 0dB is the maximum) of its maximum output value as shown below. Here we have used the 40dB line as an example. The -3dB or 70.7% of Vmax down point from the frequency response curve is given as 37dB.

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.
