Operational amplifiers — or op amps, as you probably call them — have long been a key building block in analog circuits. It’s true even in our digital age as op amps are tapped to handle useful ...

A family of operational amplifiers featuring a gain-bandwidth product of 100 kHz typically requires an ultra-low quiescent current of 600 nA and a maximum quiescent current of just 1 µA. Microchip ...

In designs using multiple LED strings such as brake lights, daytime running lights, rear lights and other automotive lighting applications, current-balancing circuits supply equal current to all LED ...

KYOTO, Japan, Sept. 9, 2025 /PRNewswire/ -- ROHM Co., Ltd. has announced that its ultra-compact CMOS Operational Amplifier (op amp) TLR1901GXZ achieves the industry's lowest operating circuit current ...

If we had to pick one part to crown as the universal component in the world of analogue electronics, it would have to be the operational amplifier. The humble op-amp can be configured into so many ...

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

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

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 ...

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