Key Differentiators
- Higher accuracy grade available (vs AD5422BCPZ)
- 16-bit resolution vs 12-bit (vs AD5412ACPZ)
- Pin-compatible with AD5422 family (vs DAC8760IPWPR)
Design Notes
The AD5422ACPZ requires a clean analog supply (AVDD) and digital supply (DVDD). Use separate analog and digital ground planes and connect them at a single point. Decouple AVDD with a 10 µF tantalum capacitor in parallel with a 0.1 µF ceramic capacitor placed close to the AVDD pin. For DVDD, use a 1 µF ceramic capacitor. Ensure the supply voltage is within the 10.8 V to 40 V range to avoid damage.
For optimal performance, place the AD5422ACPZ on a PCB with a solid ground plane. Keep the analog output traces (IOUT, VOUT) short and shielded from digital signals. Use a 4-layer PCB with dedicated power and ground planes. The exposed pad on the LFCSP package should be soldered to the ground plane for thermal and electrical performance. Follow the layout guidelines in the AD5422 datasheet (Rev. P) for best results.
A common mistake is neglecting the reference input. The AD5422ACPZ can use an internal reference, but for best accuracy, use an external precision reference. Also, ensure the serial interface timing meets the specifications in the datasheet. The CLEAR pin should be tied to a known state to avoid unintended resets. Additionally, the FAULT output should be monitored in software to detect overcurrent or overtemperature conditions.
