AD5122ABRUZ100 Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a low-ESR capacitor for decoupling and place it close to the device.
  • Calibrate the device by applying a known temperature and adjusting the offset and gain registers accordingly. Use a thermocouple or a precision temperature sensor as a reference. Ensure good thermal contact between the device and the heat source.
  • The maximum allowed voltage on the VDD pin is 5.5V. Exceeding this voltage may damage the device. Ensure that the power supply voltage is regulated and within the recommended operating range.
  • Use a 3-wire SPI interface to communicate with the device. Ensure that the microcontroller's clock frequency is within the recommended range of 1 MHz to 5 MHz. Use a level shifter if the microcontroller's voltage is not compatible with the AD5122ABRUZ100's voltage.
  • The thermal resistance of the AD5122ABRUZ100 package is typically 30°C/W. This value can be used to estimate the junction temperature of the device based on the ambient temperature and power dissipation.
