AMT49406GLPTR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the sense lines as short as possible and away from noise sources.
  • Use a low-pass filter with a cutoff frequency of around 100 kHz to filter out high-frequency noise. You can also use a capacitor in series with a resistor to filter out high-frequency noise.
  • Power on the VCC pin first, followed by the VDD pin. This ensures that the internal voltage regulators are powered up correctly.
  • Use the built-in self-test feature to calibrate the device. Apply a known magnetic field and adjust the offset and gain registers to achieve optimal accuracy.
  • The maximum operating temperature range is -40°C to 150°C. However, the device is typically specified for operation up to 125°C.
