Web18 de set. de 2024 · OpAmps have excellent Rout at low frequencies, with that Rout increasing continually above the open loop gain rolloff frequency, often 10Hz or 100Hz. The increase in Rout also shows a 90 degree phase shift. Result is the OpAmp has inductive Zout, above that 10Hz or 100Hz corner frequency. Web22 de jan. de 2016 · Op amps are not usually designed to drive a large capacitive load. The capacitance interacts with the open-loop output impedance, R O, of the amplifier to introduce a pole, fp O1, in the amplifier’s open-loop gain curve, as shown in Figure 3. This pole causes excessive phase shift in the feedback loop, severely degrading phase margin.

WebLearn more about capacitive load compensation. There are applications in which an op-amp drives a heavily capacitive load: typical examples are sample-and-hold amplifiers, peak … Web30 de mai. de 2024 · Most op-amps will effectively drive a capacitive load providing there's a series output resistor used. Given also that your application doesn't involve negative feedback (you are operating as a comparator) there should be realistically no problems of instability leading to oscillations to worry about. high school dxd opening gif
