It seems deceptively simple to establish galvanic isolation with the help of optocouplers between circuits that operate at different ground potentials. Optocouplers draw power from the isolated ...

Deep in the heart of your latest project lies a little silicon brain. Much like the brain inside your own bone-plated noggin, your microcontroller needs protection from the outside world from time to ...

This simple scheme is based on the circuit shown below (Figure 1) in my recent article [1]. Figure 1 Using common transistor optocoupler to achieve a tube-like sound. It is known that the main feature ...

Switching power supplies, operating directly from input power lines, are generally required to have their outputs galvanically isolated from the input, in order to reduce the danger of electrical ...

Standex-Meder Electronics announces its new ATEX optocoupler for intrinsically safe circuits. The optocoupler series are tested and certified for extreme/harsh environments such as potentially ...
