With both current and voltage feedback operational amplifiers (op amps) available to the system designer, how do you select which device to use? This two-part article discusses applications most ...

Transistors often find use as three-pin amplifier devices, in which the input and the output share one pin. Thus, the input and the output must have the same voltage at this pin. On the other hand, a ...

This file type includes high-resolution graphics and schematics when applicable. Most data-acquisition systems with wide dynamic range need a method of adjusting the input-signal level to the ...
