In summary, isolators are used to protect both human interface and sensitive logic circuits from high voltage equipment, provide level translation between circuits or systems with different operating voltages, break ground loops to maintain signal integrity, and withstand common mode voltage to prevent false triggering or misinformation. There are many different isolator technologies in the market and even level translators can be used where appropriate. Market trend in the past years is showing more adoption of digital isolators due to its inherent advantages like lower power consumption, stable performance over time and temperature, and higher bandwidth. With the six channel 600V MAX14850, it joins a family of Analog Devices digital isolators where the channel configuration provides the flexibility of isolating many different serial transceivers all in one package. It is also suitable for applications where the working voltage is less than or equal to 200V and harmonizing voltages between 3.3V and 5V systems.
