Myrra recommends a 4-layer PCB with a solid ground plane and a separate power plane for the 45002. Keep the signal traces short and away from the power plane to minimize noise and EMI.
Use a reliable communication protocol like SPI or I2C, and ensure that the clock frequency is within the recommended range. Also, add capacitors to the power lines to filter out noise and ensure a stable power supply.
The 45002 can operate safely between -40°C to 85°C. However, it's recommended to keep the operating temperature between 0°C to 70°C for optimal performance and reliability.
Use ESD protection diodes or TVS diodes on the input/output lines to protect the 45002 from electrostatic discharge. Also, ensure that the PCB is designed with ESD protection in mind, such as using a ground plane and keeping sensitive components away from the edges.
Power up the 45002 in the following sequence: VCC, then VDD, and finally the input signals. This ensures that the internal voltage regulators and bias circuits are properly initialized.
