AD7938BSUZ-6 Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD before applying VREF. This ensures that the internal reference is stable before the ADC starts converting.
  • To minimize noise and ensure accurate conversions, keep the analog and digital grounds separate, use a solid ground plane, and keep the analog input traces short and away from digital signals. Also, use a low-ESR capacitor for the VREF pin.
  • The maximum sampling rate of the AD7938BSUZ-6 is 1.5 MSPS (million samples per second). However, this rate may vary depending on the specific application and system design.
  • Yes, the AD7938BSUZ-6 can be used in a multiplexed configuration. However, the multiplexer should be designed to minimize signal degradation and ensure that the analog input signals are properly buffered and isolated.
  • The AD7938BSUZ-6 has an internal calibration feature that can be used to optimize its performance. The calibration process involves applying a known input voltage and adjusting the internal offset and gain registers to achieve optimal performance.
