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 ...

In a simplified schematic from its datasheet, Linear Technology's LTC6268 (and 6269 dual) provide no evidence of "secret sauce." Rather, it shows a combination of semiconductor design and process ...

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

The operational amplifier, or op amp, is one of the most basic building blocks used in analog circuits. Ever since single-chip op amps were introduced in the 1960s, thousands of different types have ...

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 ...
