AM0805AQ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital sections separate, and use a ferrite bead or a 10uF capacitor to filter the power supply.
  • Use the lowest possible clock frequency, disable unnecessary peripherals, and use the power-down mode when not in use. Also, consider using a low-dropout regulator (LDO) to reduce power consumption.
  • The AM0805AQ can operate from -40°C to 85°C, but the optimal operating temperature range is between 0°C to 70°C for best performance and reliability.
  • Use a metal shield or a Faraday cage to enclose the AM0805AQ, and ensure that the PCB layout is designed to minimize electromagnetic radiation. Also, use a common-mode choke or a ferrite bead to filter the power supply.
  • Use a 12MHz crystal oscillator with a load capacitance of 10pF to 20pF, and ensure that the oscillator is connected to the XTAL pins with a series resistor of 1kΩ to 2kΩ.
