A1308LLHLX-2-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.
  • The output voltage swing is dependent on the supply voltage and can be adjusted using external resistors. A voltage divider or an op-amp can be used to condition the output signal.
  • The maximum allowable current is 10 mA per pin. Exceeding this limit can cause damage to the device.
  • Use a shielded enclosure, minimize PCB trace length, and add filtering components (e.g., ferrite beads, capacitors) to reduce electromagnetic interference (EMI).
  • The operating temperature range is -40°C to 150°C. However, the device's accuracy and performance may degrade at extreme temperatures.
