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 LTC6417 from Linear Technology is a 1.6 GHz fully differential buffer amplifier with 1.5 nV/√Hz output-referred noise. Capable of driving a differential 50 Ω load, the buffer is optimized for ...
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 ...
