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. WebSome (but not all) opamps are unstable with capacitive loads, and their datasheets warn you to install a series resistor between the opamp output pin and any capacitive load. Perhaps whoever prepared your lab instructions is paranoid that your scope probe's input capacitance might load down the opamp output and create instability. EXAMPLE
