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 ...

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 ...

Optocouplers, also known as opto-isolators, are components that transfer electrical signals between two isolated circuits by using infrared light. As an isolator, an optocoupler can prevent high ...

Southwest Research Institute has developed a high-reliability, high-voltage optocoupler for spaceflight applications. NASA has selected the device as a power interface between the Europa Clipper ...

Designers of switch-mode power supplies generally put a lot of care into selecting the placement of poles/zeros of the supply transfer function to ensure stable operation. However, many such designs ...

New automotive-grade optocouplers deliver higher isolation voltage, longer creepage distances, and improved thermal ...

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 ...

WAGO Corporation’s DIN-rail mount 859-940 High-Speed Optocoupler features a frequency input range of up to 1.5MHz. Engineered by WAGO’s Custom Products Division, 859-940 provides jumper-selectable, ...

Over the years we’ve seen several attempts at adding Internet connectivity to the lowly wired doorbell. Generally, these projects aim to piggyback on the existing wiring, bells, and buttons rather ...

Optocoupler biasing is a critical yet often overlooked aspect of isolated SMPS design. Ensuring proper biasing of both the LED and phototransistor sides of the optocoupler is essential for maintaining ...
