An op-amp has a low-frequency open-loop gain of 5 times, Ask an Expert

Engineering

An op-amp has a low-frequency open-loop gain of 5 × 10⁴ and a dominantpole frequency of 10 Hz. Using this op-amp, design a preamplifier system that can amplify the output of a microphone and produce a 1 V peak signal over a frequency range from 10 Hz to 15 kHz.

The equivalent circuit of the microphone is a voltage source in series with an output resistance. The voltage source produces a 5 mV peak signal and the output resistance is 10 k Ω.
