The 741 op-amp IC, priced under $1, came to market in 1968, moving the device from novelty to the mainstream of design. See Fig. 1 for the functional diagram of the 741. Focusing on just linear ...

Looking at the circuit diagram it follows the classic op-amp with a long-tailed pair of NPN transistors driving a PNP gain stage and finally a complimentary emitter follower as an output buffer.

If you have read my first blog, you may have noticed that I really like op amps. My primary expertise lies in designing them, but I’m also intrigued by clever op-amp application circuits. To promote ...

Figure 2 shows the Figure 1 circuit with the tenfold reduction in closed-loop gain accomplished by changing the op-amp input resistor to 11 k Ω. However, with this approach, you will face a ...

Consider a differential op-amp circuit that has a positive input with gain of +5 and a negative input with gain of –5 (Fig. 1). R F was selected to be 100 kΩ.

Question Posed in the Last Issue (Exam Level: CBT) (click thumbnail)In the schematic, what component or components sets the amplifier stage gain? a. The gain is set by the chip itself and can be ...

You all will be familiar of basic comparator using a Op-Amp circuit. So today we will show you how to move a trip point of a Op-Amp comparator circuit. Maybe many of people already know this, but ...
