AD7858ARZ Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD first, followed by VREF, and then the clock signal. This ensures proper initialization of the device.
  • To optimize the analog input impedance, use a buffer amplifier with a high input impedance (>10 kΩ) and a low output impedance (<100 Ω) to match the AD7858ARZ's input impedance.
  • The maximum clock frequency for the AD7858ARZ is 2 MHz. Exceeding this frequency may result in reduced performance and increased power consumption.
  • The AD7858ARZ outputs data in a 16-bit, two's complement format. Ensure that your microcontroller or digital system is configured to handle this format correctly.
  • The VREF pin sets the analog-to-digital converter's (ADC) reference voltage. Connect a stable voltage source (e.g., 2.5 V or 5 V) to this pin to set the ADC's full-scale range.
