The LM358 op amp can be a single or dual supply op-amp. This mean that it can operate with just a single supply i.e. + 5 volt or with dual supplies i.e. (+ and -) 5 volt supplies. With a non-inverting configuration with dual supplies (+5v and -5v) being supplied to the LM358 Please answer the following questions.1.What is the gain formula for a non inverting op amp?2.With this configuration, is there a maximum output voltage peak to peak, if so what would it be?3.This op amp is configured for a gain of 11. Input signal is an AC sine wave signal. What is the maximum AC peak to peak voltage input?4.What happens to your output signal when the input signal is above the maximum peak to peak input voltage?
