The whole point of using an isolated power supply is to isolate both the ground and power. The wiring inside the isolator is very similar to the audio isolator circuit, the only difference is that now connectors are antenna connectors and the transformer is the one designed for antenna signals (described above). ![]() However, your design is not going to work because you didn't isolate the ground. It had three turns of thin wire in promary and secondary wrapped around small ferrite core.

If you really wish to not use a transformer, one possible solution is to use a isolation power supply for your amplifier circuit. Once we've built everything and tested the circuit, we'll add an Arduino Uno to the mix and create an isolated signal output. In the following experiment, let's learn how to build an isolated circuit using a handful of components, one power supply, and a breadboard. Google Patents US5146506A - Isolator circuit for an audio system The gap provides the isolation barrier needed to remove ground loops. Combining high speed CMOS and monolithic air core transformer technology, this isolation component provides outstanding performance characteristics and is easily integrated with low and full speed USB-compatible peripheral devices. ![]() A 4KV protection system (ESD) is also integrated, allowing to protect the devices connected to the insulator.US5146506A - Isolator circuit for an audio system The ADuM3160 is a USB port isolator, based on Analog Devices, Inc., iCoupler® technology. In short, this product solves the problems of distortion and noise that can be caused by a long connection or a difference in electrical potential. To do this, the circuit integrates a unique impedance conversion and spectrum isolation system with anti-EMI capabilities. This allows a large transmission distance to be achieved without distortion. The simplest and most common way to do the isolation is use audio transformer which is ment for audio use. Ground loop interference and shifting grounds can cause a. This stereo XLR isolation transformer isolates the audio signal (input/output from the ground) in order to considerably reduce interference and therefore noise. or more devices in the same circuit have different ground potentials with respect to one another. ![]()
