Op amp high capacitive load

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.
