ADT7475ARQZ-REEL Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. The thermal pad should be connected to a large copper area on the PCB to dissipate heat efficiently.
  • Calibrate the device using the CAL pin, and ensure that the thermal sensor is in close proximity to the device being monitored. Also, minimize thermal gradients and ensure good thermal coupling between the device and the thermal sensor.
  • The maximum allowed thermal resistance is 10°C/W. Exceeding this value may result in inaccurate temperature measurements.
  • Yes, but the remote sensor should be within 10 inches (25 cm) of the ADT7475. Longer distances may result in signal degradation and inaccurate temperature measurements.
  • Use a low-pass filter or a Schmitt trigger to condition the digital output signal. Also, ensure that the PCB layout is designed to minimize electromagnetic interference (EMI).
