LTC2945HUD#PBF 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 grounds separate and connect them at a single point. Use short, wide traces for power and ground connections.
  • Use a sense resistor with a low temperature coefficient and a high power rating. Ensure the sense resistor is placed close to the device and the PCB traces are short and wide. Calibrate the device using the internal calibration feature.
  • The maximum cable length for the I2C interface is 10 meters (33 feet) with a maximum capacitance of 400 pF. Use a twisted pair cable with a shield connected to GND.
  • Use a low-pass filter or a ferrite bead on the power supply lines to reduce high-frequency noise. Add decoupling capacitors close to the device to filter out high-frequency noise.
  • Yes, the LTC2945HUD is rated for operation up to 125°C. However, ensure proper thermal design and heat sinking to prevent overheating. Use a thermal interface material and a heat sink with a thermal resistance of less than 10°C/W.
