AD1940YSTZRL Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital sections separate, and use a star-grounding configuration to minimize noise.
  • Use a reliable communication protocol like SPI or I2C, and ensure proper signal termination and buffering. Also, consider using a dedicated communication IC or a microcontroller with a built-in communication peripheral.
  • Power up the analog supply (AVDD) first, followed by the digital supply (DVDD). Ensure that the analog supply is stable before applying the digital supply.
  • Use a high-speed clock buffer or a dedicated clock distribution IC to ensure signal integrity and minimize jitter. Also, consider using a clock domain crossing (CDC) circuit to synchronize the clock signal.
  • Use a heat sink or a thermal pad to dissipate heat. Ensure good airflow around the device, and consider using a thermal interface material (TIM) to improve heat transfer.
