In this question, an op amp is used to amplify the audio output from a music player and drive a pair of headphones, as shown. Find the maximum circuit gain (vo/vi) that can be used while simultaneously achieving a circuit 3-dB bandwidth of at least 100 kHz. 20 V/V 50 V/V 100 V/V 75 V/V 10 V/V Op-amp parameters: Ao = 2x10^5 V/V ft = 10 MHz Slew Rate = ∞ V/µs vo max = ± 14V
