If you have read my first blog, you may have noticed that I really like op amps. My primary expertise lies in designing them, but I’m also intrigued by clever op-amp application circuits. To promote ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

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 ...

My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...

The term rail-to-rail refers to the ability of an op amp to achieve an output or input that can vary over the full range of the dc supply voltages. This feature is realized with CMOS circuits. For ...

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 ...

b. The gain is set by VCC as the higher the supply voltage, the higher the gain. c. By the value of R3 as this resistor to ground sets the offset bias seen by the op-amp hence the gain. d. By the ...

Minimizing the noise effects of electric and magnetic fields on op-amp circuits does not require a magician. A step-by-step procedure can tame such interference. Once you understand the basis of noise ...

According to ROHM, its ultra-compact TLR1901GXZ CMOS op amp is the industry’s lowest operating circuit current. The op amp is built to be used as a measurement-sensing amplifier in space-constrained ...

ROHM Semiconductor today announced the development of the TLR1901GXZ, an ultra-compact CMOS operational amplifier (op amp) that achieves the industry’s lowest operating circuit current. Optimized for ...

Moreover, the TLR1901GXZ features an exceptionally low input offset voltage of just 0.55mV (max.), one of the best among ultra-low current op amps. A maximum input offset voltage temperature drift of ...
