AD7887ARMZ 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.
  • Use a low-pass filter or a buffer amplifier to drive the analog input pins to reduce noise and improve signal integrity. Also, ensure that the input signal is within the specified voltage range.
  • The maximum sampling rate of the AD7887 is 125 kSPS. However, the actual sampling rate may be limited by the system clock frequency and the conversion mode.
  • The BUSY signal goes high during conversion and returns low when the conversion is complete. You can use this signal to synchronize your system with the ADC's conversion process.
  • The VREF pin is the reference voltage input for the ADC. Connect a stable voltage source (typically 2.5V or 5V) to this pin, and ensure that it is decoupled with a capacitor to reduce noise.
