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 ...

The current differencing buffered amplifier (CDBA) is a derivative of the current feedback operational amplifier (CFOA), originally proposed by Acar C and Ozoguz S. The main advantage of a CDBA is ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...

Texas instruments has revealed a buffer amplifier developed especially for oscilloscope inputs from dc to GHz. Texas instruments has revealed a buffer amplifier developed especially for oscilloscope ...
