Key Differentiators
- Higher isolation rating than many competitors (vs ADUM3190ARQZ)
- Precision 400 mV reference with ±1% accuracy (vs ADUM3190BRWZ)
- Wide supply voltage range (3V-20V) (vs ADUM3190ARQZ)
Design Notes
For the ADUM3190ARWZ, maintain proper creepage and clearance distances on the PCB to meet the 2.5 kV isolation rating. Use a minimum of 8 mm creepage between primary and secondary side traces. Place the device with a slot or barrier under the IC to enhance isolation. Follow the layout guidelines in the ADuM3190 datasheet.
The ADUM3190ARWZ requires a bypass capacitor of at least 0.1 µF on both VDD1 and VDD2 pins, placed close to the device. For noisy environments, use a 1 µF capacitor in parallel. Ensure the supply voltage stays within 3.0 V to 20 V to avoid damage. The quiescent current is 1.2 mA, so power dissipation is minimal.
Do not exceed the absolute maximum ratings, especially the isolation voltage. Ensure the reference pin is not loaded beyond its specified current. The COMP pin requires external compensation components for stable operation; refer to the datasheet for typical values. Avoid routing high-speed digital traces near the analog inputs to prevent noise coupling.
