AD7822BNZ Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VREF, and then the digital inputs. This ensures that the internal voltage references are stable before the digital inputs are applied.
  • The BUSY signal goes high during conversion and returns low when the conversion is complete. The microcontroller should monitor the BUSY signal and wait for it to go low before initiating a new conversion or accessing the data.
  • The maximum sampling rate of the AD7822BNZ is 200 kHz. However, this rate can be affected by the clock frequency, conversion mode, and other factors. Refer to the datasheet for more information.
  • Yes, the AD7822BNZ allows the use of an external reference voltage. The external reference voltage should be connected to the VREF pin, and the internal reference voltage should be disabled by connecting the REFSEL pin to VCC.
  • The AD7822BNZ has a self-calibration feature that can be initiated by setting the CAL pin high. The device will then perform a self-calibration sequence and adjust its internal offset and gain errors.
