An optimized, basic op amp offers precise sensor-output performance while negating temperature-induced drift and errors.

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 ...

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 ...

Of digital electronics, a wise man once said that “Every idiot can count to one.” Truer words have rarely been spoken, because at the end of the day, every digital circuit is really just an analog ...

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 ...

Q. Why buy an expensive comparator when an op amp is just as good? A. Because it isn't. My advice to anyone tempted to use an operational amplifier (op amp) as a comparator is the same as Mr. Punch's ...

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

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 ...

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 ...

Picking up where we left off in Part 1, we need to explore some methods to mitigate problems caused by unpredictable ground currents.
