When I simulate the input impedance at 20kHz by applying a voltage and measuring the current then calculating the impedance calculates to ~2MEG this seems low.
I this a correct method to simulate the input impedance?
Thanks
Hello Da,
Welcome to e2e :)
The spice models show typical specifications already in the datasheet:
But if you would like to run the test in simulation the procedure is described in AN-1516 SPICE Universal Test Circuits
Section 2.10 shows the input impedance.
All the best,
Carolina
