In OP-AMP, signal applied to the non inverting input gets amplified output ,which is
with the
input signal.
An op-amp has a slew rate of 0.7 V/μs and a maximum peak output voltage of 5 V. The maximum operating frequency, in kHz, for the circuit is
Design a differentiator using an op-amp. The output voltage should be a square wave with 5V(peak-to-peak) andthe input voltage should be a triangular wave with10V(peak-to-peak) (1ms).
