AD1938YSTZ Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply the analog power supplies (AVDD and DVDD) first, followed by the digital power supply (DVDD). This ensures that the analog circuitry is powered up before the digital circuitry.
  • To optimize performance in a noisy environment, ensure that the AD1938YSTZ is placed in a shielded area, use a low-pass filter on the analog input signals, and decouple the power supplies with capacitors. Additionally, consider using a ferrite bead or a common-mode choke on the digital lines.
  • The AD1938YSTZ can support clock frequencies up to 192 kHz. However, the maximum clock frequency may vary depending on the specific application and the quality of the clock signal.
  • To configure the AD1938YSTZ for differential analog input mode, connect the positive analog input signal to the IN+ pin and the negative analog input signal to the IN- pin. Ensure that the common-mode voltage is within the specified range, and set the appropriate registers to enable differential mode.
  • For optimal performance, keep the analog and digital signal traces separate, use a solid ground plane, and avoid crossing analog and digital signal traces. Additionally, place decoupling capacitors close to the power pins and use a low-impedance power supply.
