I am looking for sensing AC mains current from a standard 120/240V supplies. Si85XX input frequency spec starts from 50KHz. Can I conclude that Si85XX is not the right fit here?
If the conclusion is correct, are there any other integrated solutions from Si which can sense the current through main AC 120/240V 60Hz line?
The Si85XX is intended to be used in switching supply applications and maintains accuracy at a minimum of 50kHz. For AC mains applications, please consider the Si890X isolated ADC or the Si8920 isolated analog amplifier.
