Lab #3 The Operational Amplifier | Download for quality grades |

Document Content and Description Below

Abstract The objective of this lab is to build a summing amplifier, a differential amplifier, a voltage follower, and a proportional amplifier.[6] The operational amplifier has an inverting input ... and a non-inverting input through two input terminals. The operational amplifier can also amplify the input voltage, where the degree of amplification is determined by the input resistance. Various types of circuits can be made by setting the input resistance value and the input method.[5] The four circuits were fabricated using one operational amplifier, and the LM324AN from TI instruments was used as the operational amplifier. Arduino was used as the power supply, and the voltage regulator from the second lab was used to provide 1.8v and 2.5 input voltages. To verify that the circuits work properly, the output voltages of each circuit were measured with a digital multimeter and compared to theoretical values. Introduction The Operational Amplifier used in this experiment is LM 324 from Texas Instrument (TI). This device Consist of four independent high-gain frequencycompensated operational amplifiers (Figure 0, below) [1] that are designed specifically to operate from a single supply of split supply over a wide range of voltages [2 [Show More]
