LTC2986HLX-1#PBF - Analog Devices

LTC2986HLX-1#PBF Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the LTC2986?
  A good PCB layout for the LTC2986 involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the power source. A 4-layer PCB with a dedicated analog ground plane is recommended.
• How do I optimize the performance of the internal voltage reference?
  To optimize the performance of the internal voltage reference, ensure that the VREF pin is decoupled with a 10nF capacitor to GND, and that the AVCC pin is decoupled with a 10uF capacitor to GND. Also, keep the voltage reference input pins (VIN and VREF) away from noise sources.
• What is the maximum allowed voltage on the input pins?
  The maximum allowed voltage on the input pins is 6V. Exceeding this voltage can damage the device. Ensure that the input voltage is within the recommended range to prevent damage.
• How do I handle thermal management for the LTC2986?
  To handle thermal management, ensure good airflow around the device, and consider using a heat sink if the device is expected to operate at high temperatures. The device has a thermal shutdown feature that activates when the junction temperature exceeds 150°C.
• What is the recommended clock frequency for the LTC2986?
  The recommended clock frequency for the LTC2986 is between 1MHz and 4MHz. Operating the device at frequencies outside this range may affect its performance and accuracy.
