How to isolate analog voltage
Web30 jun. 2006 · Depending on how high your DC voltage is you could either isolate analog with e.g. an ISO 122 or ISO 124 or go digital with the A/D converter on the high voltage side. In this case you could use optocouplers or better ADUM120X from Analog Devices (very fast and easy to handle). You will probably need a DC/DC converter to power … Web6 mei 2024 · Intake Air Temperature sensor is a resistor connected to the ECU forming an internal voltage divider. Want to trick ECU by telling it what the voltage (temperature) is but only sometimes. Want to splice into IAT wire and apply voltage to it using MCU via PWM. Need to filter PWM to get DC. Filter appears as a load (resistive network) to ECU.

Web5 nov. 2024 · I am aware that I could use a voltage divider like this: simulate this circuit – Schematic created using CircuitLab. The Question. Because this is for a prototype that should be up to industrial safety standards, my boss wants me to isolate the 10 V from the 3.3 V logic. I don't really know a method to do this though while reading analog signals. Web7 dec. 2024 · In such applications, analog isolation is often needed when measuring the voltage across a motor’s sense resistor to determine the current through the motor. This is necessary because the sense resistor is not ground referenced but is instead “floating”, and may be at a very high potential with respect to ground.
