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 ...

The unity-gain op amp (operational amplifier) buffer circuit is routinely used to transform high-impedance inputs into low-impedance outputs. ADC (analog-to-digital converter) voltage references are ...

Did you ever wonder how to calculate the stability of an op amp circuit? Put the wrong compensation network into the feedback loop, and you’re got an attenuator or, worse, an oscillator. It’s not ...
