Nettet4. jul. 2024 · This circuit exhibits the class b crossover notch present in the LM124 family of opamps and probably is susceptible RFI rectification on the inputs (a known weakness of these opamps). However, I believe the second (behavioral) model I provided for you is a much better choice for LTspice (it also models the LM124 family weaknesses). Nettet18. aug. 2010 · But this changed rapidly. Opamps are nowadays used all over the analog world because you - everyone! - can design reliable and predictable circuits. The rule for an opamp is as simple as this: It adjusts its output voltage in such a way that there is no voltage difference between its inputs.
