AD843AQ Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply the analog supply voltage (VCC) before the digital supply voltage (VDD). This ensures that the internal analog circuitry is powered up before the digital circuitry.
  • To optimize the layout, keep the analog and digital grounds separate, use a solid ground plane, and keep the input and output traces short and away from digital signals. Also, use a low-ESR capacitor for the power supply decoupling.
  • The maximum input voltage that the AD843AQ can handle is 30V, but it's recommended to keep the input voltage within the specified range of 0V to 28V to ensure accurate measurements.
  • The AD843AQ does not require calibration, as it is a ratiometric device that measures the ratio of the input voltage to the reference voltage. However, it's recommended to use a high-accuracy voltage reference and to ensure that the input voltage is within the specified range.
  • The AD843AQ's accuracy is affected by temperature, with a typical temperature coefficient of ±50 ppm/°C. To minimize temperature-related errors, it's recommended to use a temperature-compensated voltage reference and to keep the device within the specified operating temperature range.
