Design Notes
The AD5422ACPZ requires a clean analog supply (AVDD) and digital supply (DVDD). Use separate decoupling capacitors: 10 µF tantalum and 0.1 µF ceramic on AVDD, and 0.1 µF ceramic on DVDD. Place the capacitors as close to the pins as possible. The device can operate from a single 10.8V to 40V supply, but for best performance, keep AVDD and DVDD within 0.3V of each other.
For optimal performance, use a ground plane and separate analog and digital ground areas, connecting them at a single point. Route the IOUT and VOUT traces away from digital signals to minimize noise coupling. The exposed pad on the LFCSP package should be soldered to the ground plane for thermal and electrical connection. Follow the layout guidelines in the datasheet (Rev. P) for best results.
Ensure the reference voltage is stable. If using the internal reference, place a 1 µF capacitor on REFOUT. If using an external reference, connect it to REFIN and bypass with 0.1 µF. Do not exceed the absolute maximum ratings, especially on AVDD (40V). For HART operation, the HART signal must be AC-coupled to IOUT; ensure the HART input is driven by a proper modem. Also, the SYNC pin must be held high when not in use.
