UNDERSTANDING OPTOISOLATORS IN POWER SUPPLY AND SIGNAL ISOLATION

What Is an Optoisolator? An optoisolator isolator AK4490EQ is an electronic device that transmits signals using light, effectively isolating two circuits to prevent high voltage or noise from interfering with low-voltage circuits. Simply put, the optoisolator isolator uses a small LED to emit light, which is then received by a "light receiver" s
