YILDIRIM BEYAZIT UNIVERSITY ECE 203 - ELECTRICAL CIRCUITS LABORATORY MANUAL – 5 – BASIC APPLICATIONS OF OPERATIONAL AMPLIFIERS – PART1 Laboratory Exercise: In this laboratory you will construct and observe basic OP-AMP circuits. You will use LM741 OP-AMP. The pin layout of LM741 is given in Figure 1.
Figure 1: LM741 Pin Layout The 1st, 5th and 8th pin of LM741 will be left open while constructing your circuits. LM741 inner OPAMP connections are shown in Figure 2.
