A1326LLHLT-T Frequently Asked Questions (FAQs)

  • A symmetrical layout with a central ground plane and minimal signal trace length is recommended. Allegro provides a reference layout in their application note AN296070.
  • Use a low-pass filter or a ferrite bead in series with the output to reduce electromagnetic interference (EMI). Additionally, consider using a shielded cable or a twisted pair to connect the output to the load.
  • The maximum allowable voltage on the VCC pin is 5.5V. Exceeding this voltage may damage the device.
  • The A1326LLHLT-T is rated for operation up to 150°C. However, the device's accuracy and reliability may degrade at high temperatures. Consult Allegro's application notes for thermal management guidelines.
  • Calibration is not required for the A1326LLHLT-T, as it is a factory-calibrated device. However, you may need to adjust the output voltage using an external resistor divider network to match your specific application requirements.
