یادداشت‌های طراحی
Ensure clean and stable power supplies for the AD10465AZ. Use low-noise LDO regulators and adequate decoupling capacitors (e.g., 0.1uF and 10uF) close to the AVDD and DVDD pins. The datasheet specifies that all specifications are guaranteed within 100 ms of power-up, so proper power sequencing is not critical, but good supply filtering is essential for achieving rated SNR and SFDR.
For optimal performance, use a multi-layer PCB with dedicated ground planes for analog and digital sections. Keep analog input traces short and shielded to minimize noise pickup. The ceramic gull wing package requires careful soldering; follow recommended reflow profiles. Place the encode clock source close to the ENCODE pins and use differential routing to reduce jitter.
Avoid driving the analog inputs beyond the specified common-mode range to prevent damage and distortion. Ensure the encode clock has low jitter, as clock jitter directly degrades SNR. Also, be aware that the AD10465AZ is obsolete; verify availability and consider alternative parts for new designs. The module's signal conditioning is dc-coupled, so input offset must be managed.
