741 Op-Amp Circuit Section 8.1 (Razavi) Chapter 12 (Sedra Smith) History • The first uA741 Op-Amp was designed by Bob Widlar in 1963 at Fairchild Semidconductor. – uA702 sold for 300 a piece. – uA709 was sold for 70 a piece. • Bob asked for a raise, didn’t get it, ...
After the invention of transistors, they replaced vacuum tubes in all the possible circuits. Hence in op-amps also, the bulky vacuum tubes were replaced by the transistors. This was the beginning of designingop-amp circuitmodules. They were built in a small sized circuit board, which can be ...
IC LM741 is advanced and commonly used Op-amp as voltage amplifier. Pin diagram of LM741 is given below: Circuit Diagram and Working: Circuit is very simple and we have kept is simple with few components, which can be easily built on breadboard or on PCB. We just need to place the ...
The voltage fluctuation at the input of op-amp can impact current flow in the internal circuit and also impact the effective functional range of the transistor in the circuit. To prevent from happening this, two current mirrors are used. The transistor pair (Q8, Q9) and (Q12, Q13) are co...

The uA741 is a high performance operational amplifier with high open loop gain, internal compensation, high common mode range and exceptional temperature stability. The uA741 is short-circuit protected and allows for nulling of the 3/16 2014年10月15 日 741 Op-Amp Tutorial, op-amps, ...
Pin Configuration of 741 Op-amp Circuit Diagram 2. LM324 LM324 is a quad op amp integrated circuit with high stability, bandwidth which was designed to operate from a single power supply over a wide range of voltages. They have some dissimilar advantages over standard operational amplifier types...
Figure 1.16 shows an equivalent circuit that illustrates the effect of output impedance. The output circuit is composed of a voltage source and a series resistance (ro). You can think of this as the Thevenin equivalent for the internal circuitry of the op amp. The internal voltage source has...
