Op-amp circuits have a feedback loop, but sometimes it is advantageous to improve closed-loop performance by including another amplifier within the op amp's feedback ...

Demand for high-speed data acquisition is pressuring suppliers of analog front ends, specifically operational amplifiers, to put more features into smaller packages. Chip makers have responded with ...

The ordinary modern IC op amp is fully applicable to most standard amplifier configurations. Error sources are small and may be of no concern, or one can easily ...

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 ...

If you’re a child of the ’80s or ’90s, chances are you’ve spent hours tracing out intricate patterns using the pens and gears of a Spirograph kit. Simple as those parts may be, they’re actually a very ...

What is driving the power vs. performance tradeoffs? How to improve the op-amp bandwidth-to-power ratio. How noise, distortion, and other factors impact the power/performance design decisions. The ...

Sponsored by: Texas Instruments. Op amps solve most problems in analog circuit design—if you know how to use them. Here are some resources to help expand your op-amp knowledge base. Whenever you need ...

Power operational amplifiers (POPs) are becoming increasingly common in control circuitry. Their primary advantages over conventional amplifiers are reduced part counts, increased reliability, and ...
