The operational amplifier is arguably the most useful single device in analog electronic circuitry. When you apply them in the circuits, you must know their basics and functions. As for the function ...

The term instrumentation amplifier (INA) often is misused, referring to the application rather than the architecture of the device. Historically, any amplifier that was considered precision (i.e., ...

What if a palm-sized amp could outperform larger, more expensive modules while delivering serious sound quality? Check out ...

The OPA1602 and OPA1604 bipolar-input operational amplifiers achieve very low 2.5nV/√Hz noise density with an ultralow distortion of 0.00003% at 1kHz. The OPA1602 and OPA1604 series of op amps offer ...

In the first article about measurement systems we looked at sensors as a way to bring data into a measurement system. I explained that a sensor measures physical quantities which are turned into a ...

Different classes of amplifiers. What are the benefits of class AB amplifiers? Patents that address the quiescent current of class AB amps. Amplifiers have many classifications, and each class has its ...

Are your jellybeans getting stale? [lcamtuf] thinks so, and his guide to choosing op-amps makes a good case for rethinking what parts you should keep in stock. For readers of a certain vintage, the ...
