Explanation: The coupling capacitor at the output blocks the AC output signal riding on a DC level of (+Vcc/2) volts and the resultant waveform will be AC. In non-inverting amplifier, the output will be of the same phase as that of input signal. 5. Find the maximum output voltage swing of an AC inverting amplifier using op-amp 741C?
A. +15Vpp
B. ±15Vpp
C. ±13Vpp
D. +13Vpp
Answer:A
Explanation: The coupling capacitor at the output blocks the AC output signal riding on a DC level of (+Vcc/2) volts and the resultant waveform will be AC. In non-inverting amplifier, the output will be of the same phase as that of input signal. 5. Find the maximum output voltage swing of an AC inverting amplifier using op-amp 741C?
A. +15Vpp B. ±15Vpp C. ±13Vpp D. +13Vpp
Explanation: The value of power supply for 741 op-amp=±15v. Therefore, the ideal maximum output voltage swing for an AC amplifier with single power supply = +Vcc = +15v. 6. Determine the lower cut-off frequency of the circuit.
