This is a 741 Op-Amp. All basic circuits with an operational amplifier, from amplifying circuits, [...] computing circuits, active filter and resonant circuits and flip-flop circuits to the familiar application circuits such as constant current source, Sample-and-Hold circuit or controller circuits can be coherently and effectively taught with the SE plug-in system in teacher-centred lessons and lectures. Pin 7 is our HIGH supply voltage, which is 5v. This means that any current flowing into the chip can be ignored. R1 RF Vin2 Vout R2 R3 Vin1 Vin3 I1 I2 I3 IF N1 Figure 1. Pin 4 is the LOW supply, which is currently at ground potential. So this will be an amplifier with some sort of gain, and if I put a signal x in here, usually a voltage or a current, then the signal that comes out here is A times x, and that's what we mean by amplification. A buffer amplifier is a block that is placed between two circuits which impedances are not matching: a high (resp. Most of these circuit configurations require the op-amp output to be connected back to its input. Pin 2 is our inverting input. Operational amplifiers with positive feedback can be used in the construction of oscillators. Op amp is basically a multistage amplifier in which a number of amplifier stages are interconnected to each other in a very complicated manner. Consider the following diagram. Hardcover.
