Design Notes
Place the shunt resistor as close as possible to the VINP and VINN pins to minimize parasitic inductance. Use a Kelvin connection to the shunt to ensure accurate voltage sensing. Keep the high-side and low-side grounds separate and connect them at a single point to avoid ground loops.
Route the differential output traces as a pair with controlled impedance to maintain signal integrity. Avoid routing near high-voltage or high-current traces to prevent coupling. Use ground planes on both sides of the isolation barrier to reduce noise.
Do not exceed the absolute maximum input voltage of ±0.5V on the input pins. Ensure the input filter components are placed close to the device to filter high-frequency noise. Verify that the output differential signal is within the common-mode range of the downstream ADC.
Compliance Information
