One way to measure the slew-rate limitation of an op amp is to apply a sine wave (or square wave) as the input to an amplifier and then increase the frequency until the output waveform becomes triangular. Suppose that a 1-MHz input signal produces a triangular output waveform having a peak-to-peak amplitude of 4 V. Determine the slew rate of the op amp.
The two input terminals of an op-amp are connected to voltage signals of strength 745µV and 740µV repectively. The gain of the op-amp in common mode is 50 and CMMR is 8&IB. Calculate the output voltage and % of error due to common mode.
