Maxim provides a recommended PCB layout in the ICM7250 evaluation kit documentation, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
To ensure accurate temperature measurement, it's essential to follow proper calibration procedures, use a high-accuracy voltage reference, and minimize thermal gradients on the PCB. Additionally, consider using a thermocouple or other temperature sensor with a high accuracy rating.
Although the datasheet specifies a maximum operating voltage of 5.5V, it's recommended to limit the voltage on the VCC pin to 5V to ensure reliable operation and prevent damage to the device.
Yes, the ICM7250 can operate with a 3.3V supply voltage, but the output voltage range will be limited to 0.5V to 2.5V. Consult the datasheet for specific operating conditions and output voltage ranges at 3.3V.
The ICM7250's POR and BOR features are designed to ensure reliable startup and operation. To handle these features, ensure that the power supply voltage ramps up slowly (typically 10ms to 100ms) and that the voltage remains above the POR/BOR threshold (typically 1.8V) during operation.
