How to choose a signal isolator?

Analog isolator is an electronic component used to isolate analog signals between two circuits to prevent interference between circuits. It usually consists of two analog signal converters, which can convert analog signals into digital signals and then convert them back into analog signals to achieve isolation. Signal isolator is a kind of linear optocoupler isolation…
