TI, which is entering the optocoupler market for the first time with its digital-output ISOM8710 and ISOM8711 and the analog-output ISOM8110, said they can slot into virtually any high-voltage ...

If the optocoupler is current-starved, the output voltage will keep rising until the proper amount of LED current conducts through the optocoupler. This results in overvoltage conditions on the output ...

A 4N25 optocoupler boasts an isolation test voltage of 5,000 V between the LED and transistor. If you put 500 V across it, you would see an effective resistance of more than 10 12 Ω.

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 ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

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 ...

The linear optocoupler offers low input-output capacitance of 1 pF typical, high gain linearity of ± 0.25 %, and low power consumption of < 15 mW. In addition, the device features an operating ...

The correspondingly low CTR associated with a low-frequency optocoupler pole will not hurt the performance at the end, as long as their natural variations are well accounted for in the design cycle.

An optically isolated sigma-delta modulator, the Avago ACPL-C799 from Broadcom, claims to convert an analogue input signal into a high-speed data stream with galvanic isolation. It features a low ...

STMicroelectronics is has chosen an isolated buck converter topology for a 10W dc-dc converter that provides a regulated local primary power rail, plus a moderately regulated isolated secondary power ...
