An audio amplifier is to be produced using a 741 op-amp. What is the maximum gain that can be achieved using this arrangement if the amplifier must have a bandwidth of 20 kHz?
Step-by-Step
For a 741
gain × bandwidth = 10^{6}
Therefore, if the bandwidth required is 2 × 10^{4} , then the maximum gain is given by
gain = \frac{10^{6}}{bandwidth} = \frac{10^{6}}{ 2 × 10^{4}} = 50Related Answered Questions
