Analog isolation
Isolating an analog signal is a challenging task, there is no single component that can do this. The Gravity™ Analog Isolator uses three components to achieve this, a voltage isolator, a PWM generator, and an Opto-isolator. The Voltage Isolator is needed to supply the Gravity™sensor. The PWM generator converts an analog signal to a square wave, which can then pass through the Opto-isolator.
