WebResponse of AD8061 as a zero-crossing comparator. In Figure 8, the AD8061’s step response is compared with that of the popular LM139, and two other open-loop amplifiers, connected in the same circuit configuration as in Figure 6. As can be seen, the AD8061 responds within 300 ns, which is faster than LM139. WebFigure 1: Op-amp Circuit. The fundamental function of an op-amp is to greatly amplify the differential between the two inputs, and output the result. If input at V (+) is greater than at V (−), the op-amp will amplify and output a positive signal; if V (−) is greater, the op-amp will output an amplified negative signal.
