How can i use the AD7403 to measure current on the high side of the motor phase.?
I have used current sense resistor in series with motor phase windings. My DC Link voltage is 170V.
And I have connected the two ends of the current sense resistor to the input pins of AD7403 (vin+ and vin-).
The IC is getting damaged when I am switching on the DC link voltage. I have used isolated power supply for the analog side of the IC(VDD1) ?
