Key Differentiators
- Basic isolation with 3kVRMS rating (vs AMC0302D)
- Fixed gain of 8.2 V/V (vs AMC0380D)
- High CMTI of 100 kV/µs (vs ISO7830DW)
Design Notes
Place the shunt resistor as close as possible to the IN+ and IN- pins to minimize parasitic inductance. Use Kelvin connections 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 symmetrically and keep them away from high-voltage switching nodes. Use a ground plane on the low-side to reduce noise coupling. For best performance, place decoupling capacitors (0.1µF) close to VDD1 and VDD2 pins.
Do not exceed the absolute maximum input voltage of ±50mV, as this can damage the device. Ensure the input filter components are placed before the shunt to reject high-frequency noise. The differential output should be terminated properly if driving a high-speed ADC to avoid reflections.
