Comprised of two precision op amps (MAX4236), a voltage reference (MAX6143), a NAND gate, and associated components, this DC-voltage detector circuit asserts a digital output signal when the input is ...

There are two groups of classic circuits: those which have served us well in the past, but have been superseded by better designs, and those which are still in use, perhaps with updated components. In ...

Environmental systems that precipitate dust and carbon particles frequently use high-voltage dc power supplies. However, failure of high-voltage components caused by a change in their properties over ...
