Purpose of experiment To model and measure an operational amplifier circuit with a set input-output range. Model numbers of equipment used HP33210A Waveform Generator Agilent 54622D Mixed Signal Oscilloscope Hewlett-Packard HP34401A Multimeter Hewlett-Packard HPE3631A Power Supply Jameco JE30 Breadboard Circuit Schematics DC Source: U 1 O P A M P + - O U T R 1 1 . 8 k R 2 1 0 k R 3 6 . 8 k R 4 1 k V 1 1 5 V V i n V o u t AC Source: U 1 O P A M P + - O U T R 1 1 . 8 k R 2 1 0 k R 3 6 . 8 k R 4 1 k V o u t V i n V 1 A C = 1 0 0 m V D C = 1 7 4 m V Block diagram of test set up DC Source: AC Source:
Test Procedure Equations used % error = (measured – theoretical) / theoretical * 100 (V B – V A )/(V 2 – V 1 ) = G V y = V A – GV 1 V + = V y / (1 – G) V + = V s (R 4 / (R 3 + R 4 )) G = -R 2 /R 1 DC Source After the resistors necessary to take a 1-3V input range and transform it into a 7.2- (-4.8)V output range were derived (visible in the Circuit Schematics above), the circuit
