Lm324 Non Inverting Amplifier Circuit. This amplifier operates over a wide range of power supply voltage with little change in performance characteristics. Normally the input voltage on op amp lm324 is 0 2 0 4 v and always the output voltage is under 3 7 3 8 v.
The square wave generating circuit is relatively simple. See figure 3 below. Normally the input voltage on op amp lm324 is 0 2 0 4 v and always the output voltage is under 3 7 3 8 v.
The voltage at pin 3 non inverting input will be the same as the voltage at pin 2 inverting input.
In this output of lm324 is internally connected to some resistance and it has some arrangement inside the ic which makes a lot of difference to other comparators. By the way the answer to the challenge question may only be realized if students recognize this circuit as a non inverting opamp voltage amplifier. The lm324 n mil device is an op amp which operates with only a single power supply voltage has true differential inputs and remains in the linear mode with an input common mode voltage of 0 vdc. Iii lm324 non inverting ac amplifier circuit.
