AD7863ARSZ-3 Frequently Asked Questions (FAQs)

  • A good layout and routing practice for the AD7863ARSZ-3 involves keeping the analog and digital grounds separate, using a star-ground configuration, and placing the analog and digital components on opposite sides of the board. Additionally, it's recommended to use a solid ground plane, keep the signal traces short and direct, and avoid running digital traces near analog traces.
  • The AD7863ARSZ-3 has an internal 2.5V reference voltage that can be enabled by connecting the REFOUT pin to the REFIN pin. The internal reference voltage can be adjusted by connecting an external resistor divider network between the REFOUT pin and the REFIN pin. The datasheet provides a formula to calculate the required resistor values for a specific reference voltage.
  • The AD7863ARSZ-3 can achieve a maximum sampling rate of 250 kSPS (kilosamples per second) in parallel mode and 125 kSPS in serial mode. However, the actual sampling rate may be limited by the system's clock frequency, the conversion time, and the settling time of the analog input signal.
  • The AD7863ARSZ-3 has a power-on reset (POR) function that resets the device when the power supply voltage falls below a certain threshold. The brown-out reset (BOR) function resets the device when the power supply voltage falls below a certain threshold for a certain duration. To handle these functions, it's recommended to use an external reset circuit that can detect the power supply voltage and generate a reset signal to the AD7863ARSZ-3.
  • A good power supply decoupling scheme for the AD7863ARSZ-3 involves using a combination of ceramic and electrolytic capacitors to filter out high-frequency noise and low-frequency ripple. A 10 uF ceramic capacitor and a 10 uF electrolytic capacitor in parallel can be used to decouple the power supply pins. Additionally, it's recommended to use a ferrite bead or a power inductor to filter out high-frequency noise.
