The main function of an instrumentation amplifier is the amplification of differential signals while rejecting unwanted common-mode interference. This function proves particularly useful for ...

[John Miller] has the perfect response next time he complains about an ache or pain and one of his friends says, “You should listen to your body!” As you can see in the video below, he already does.

Op amps are the fundamental building blocks of analog circuits; you can build all analog functions from op amps. Add digital output circuitry to an op amp to get a comparator that can also function as ...

Figure 1 shows a benign means of interfacing a low-level, wideband differential signal to an analog-to-digital converter (ADC). The FET input stage (AD8066) draws only 6 pA of input bias current and ...

Measuring the body’s electrical signals is a neat trick… if you can get your equipment dialed in enough to establish dependable measurements. The technique is called Surface ElectroMyography (SEMG) ...

High-side current-sense amplifiers (CSAs) are principally used for monitoring the current from a positive supply rail. However, applications like ISDN and telecom power supplies require CSAs that ...
