11/14/2023 0 Comments Analog opto isolator![]() Since transformers often have a large inductance, they will be able to resist sudden energy spikes (such as those found from electrostatic discharge or ESD), but mains surges may be harder to resist (as they are in the low-frequency domain).Īnother issue with transformers is that they operate in the AC realm, and since energy transfer only occurs during a change in magnetic field strength, DC analog voltages cannot be isolated using this method. The first is that while the two are electrically isolated, surge energy can be transmitted across the transformer. While these two coils are electrically isolated from each other, this type of isolation has its issues. Two coils that are magnetically coupled via an iron core can transfer energy to each other via the magnetic field. One method that can provide some form of analog isolation is the transformer. So, how can an analog signal be isolated and what advantages / disadvantages are typically associated with all the many isolation solutions out there? Where the digital world consists of only 1’s and 0’s which are easy to transfer non-electrically (presence / no presence of light), analog signals have an infinite range whose value needs to be preserved. This type of isolation is very easy to achieve in the digital world with devices such as optoisolators, but the analog world can provide challenges. The result is that any surge experience by the electrocardiogram cannot be transferred to the electrodes as the electrodes are electrically isolated (that is, there is no direct electrical connection). For instances such as this, circuitry requires isolation, whereby the electrodes attached to the patient are electrically isolated from the mains powered electrocardiogram. But attaching electrically conductive electrodes across a patient’s chest can be potentially fatal during events such as an electrical surge, where the surge finds its way across the patient and therefore causes cardiac arrest. ![]() Unlike optical heart rate methods, the electrocardiogram can provide significantly more information, including unusual heart patterns and weak beats. The electrocardiogram is unique in that it uses conductive pads connected to a patient to measure the electrical pulses generated by the heart as it beats. One common example is the electrocardiogram. However, some applications may deal with highly sensitive applications that can require electrical isolation. ![]() ![]() ![]() Implementing circuit protection can be done using a wide variety of methods, including current limiting resistors, Zener diodes, and fuses.
