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 ...

A few months ago, I wrote a Signal Chain Basics article titled “3 considerations when selecting an op amp.” While that article is very useful for selecting operational amplifiers (op amps) for new ...

The operational amplifier (op amp) is the fundamental building block of all types of analog circuits. There are literally thousands of different ones available from dozens of vendors, ranging from ...

Op-amp performance is disrupted by EMI in a variety of ways. Reducing EMI in amplifiers using filters. How to mitigate EMI in Class-D audio amps. In this article, electromagnetic interference (EMI) ...

Power operational amplifiers (POPs) are becoming increasingly common in control circuitry. Power operational amplifiers (POPs) are becoming increasingly common in control circuitry. Their primary ...

What applications require precision op amps? Precision amplifiers originally evolved to fill the needs of the test and measurement community. This arena demanded test system elements with much more ...

We thought it was time to give the analog side of Hackaday their chance to shine, and what’s the quintessential analog IC? The op amp! Whether you’re doing tricky signal conditioning, analog ...

Comparison of Low-Power Op Amp Characteristics ROHM's TLR1901GXZ ranks among the best in ultra-low current op amps at approximately 45% lower than typical products on the market. Santa Clara, CA and ...
