Which Type of Opto-Isolator Is Right For Your Circuit?
An optoisolator is an electronic device that can be used to pass information between a diode without passing an electrical current. Because there is no need to directly pass voltage or current between the inputs and outputs in an optoisolator circuit, these components can be used to provide electrical isolation in two regions in a PCB. Opto-isolators act as a protection mechanism, ensuring that harmful electrical currents cannot flow across the

Methods of Circuit Protection
Overvoltage, overcurrent, and heat are the three most likely events that can destroy our expensive silicon-based components or reduce our product’s life expectancy. The effects are often quite instant, but our product might survive several months of chronic overstress before giving up the ghost in some cases. Without adequate protection, our circuit can be vulnerable to damage, so what should we do? Or do we need to do anything? For instance, if

Low-Cost Verification for Digital and Analog Filters
In Low Cost Solutions for Automated Hardware in the Loop Testing , we reviewed the idea of using low-cost testing devices to validate our hardware designs. In this article I want to zoom in on a specific application that can have a high barrier to entry when it comes to verification: Digital Signal Processing (DSP) , specifically signal filtering. Rather than belabor the topic of DSP I will define it simply as “digitizing signals that come into

The Best PCB Design Software Downloads
There are many PCB design software packages available for download or purchase. Newer designers and startups who are just starting out will likely build up their skills from a free software program just to get to a proof of concept and initial design of a prototype. Once a design has been proven and it is time to design for a real product, a new designer or startup startup company will need to make the switch over to a paid software package. To
