WebWe can always calculate the bandwidth with the following formula. (1) In the case of ADA4004, the gain bandwidth product is 12 MHz. This means that, at a gain of one, the bandwidth is 12 MHz, and at the maximum open-loop gain of 500000, the bandwidth is 12 MHz divided by 500000, which is 24 Hz. This is the op amp open-loop cutoff frequency. WebFeb 1, 2024 · The correct term to use to find Bandwidth is Rise Time (10~90%) BW=0.35/tR which is not current limited by external load capacitance, rather it is limited by internal unity-gain compensation capacitance. Thus using Gain*BW = unity gain BW Slew Rate is the result of current limiting at a specified load capacitance.
