AD7661ASTZ 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 AD7661ASTZ is 250 kSPS. However, the actual sampling rate may be limited by the system's clock frequency, analog input bandwidth, and other factors.
  • The BUSY signal goes high during conversions and low when the conversion is complete. You can use this signal to synchronize your system's operation with the ADC's conversion process.
  • The NOISE reduction pin (NR) is used to reduce noise in the ADC's conversion process. When NR is tied to VDD, the ADC uses a slower, more accurate conversion mode. When NR is tied to GND, the ADC uses a faster, less accurate conversion mode.
