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.
The AD22035Z has an internal calibration circuit. To ensure proper calibration, apply a stable voltage reference and allow the device to settle for at least 10ms before taking measurements. Also, ensure the device is operated within the recommended temperature range.
The AD22035Z is sensitive to power supply noise. It's recommended to keep the noise on the power supply lines below 10mV peak-to-peak to ensure accurate measurements.
Yes, the AD22035Z can be used in a ratiometric configuration. This involves using the same voltage reference for the ADC and the sensor, which can improve accuracy and reduce errors.
The AD22035Z outputs 16-bit data in a 2's complement format. Ensure your microcontroller or processor can handle this format and perform any necessary data manipulation, such as sign extension or scaling.
