Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with ...

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 ...

For example, much has been written on how to stabilize op amp circuits with excessive capacitive loading. My favorite reference on op amp circuits is Stout & Kaufman’s Handbook of Operational ...

As mentioned, the gain is independent of the supply voltage. For more about op-amps, see Op-Amps Are Used Widely in Broadcast Circuits Note: The deadline to sign up for the next SBE certificate exams ...

For instance, if an op amp uses ±5-V supplies, the output can swing over the full range from – 5 V to + 5 V or 10 V. For a single-supply op amp, the range would be 0 to + 5 V.

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 ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input res… ...

A note: For convenience, that is also where the op-amp diagram (top) came from – the one in the diagram is a 8MHz rail-to-rail op-amp, surely over-kill for such an application, when cheap slow 30V ...
