VTI Technologies recommends a 4-layer PCB with a dedicated ground plane and thermal vias to ensure optimal thermal management. A minimum of 2 oz copper thickness is recommended for the top and bottom layers. Additionally, a thermal pad on the bottom of the device should be connected to a large copper area on the PCB to dissipate heat efficiently.
The SCA620-CF8H1A requires calibration to ensure accurate measurements. VTI Technologies provides a calibration procedure in the application note AN-SCA620-001, which involves applying known accelerations and rotations to the device and adjusting the internal registers accordingly.
While the datasheet specifies an operating temperature range of -40°C to 85°C, VTI Technologies recommends derating the device's performance at temperatures above 70°C to ensure reliability and accuracy. It's essential to consider the application's thermal environment and potential hotspots when designing with the SCA620-CF8H1A.
The SCA620-CF8H1A is not designed for safety-critical applications and does not meet the requirements for functional safety standards such as IEC 61508 or ISO 26262. VTI Technologies recommends using alternative devices that are specifically designed and certified for safety-critical applications.
To minimize EMI and RFI, VTI Technologies recommends using a shielded enclosure, keeping the device away from high-frequency sources, and using a low-pass filter on the power supply lines. Additionally, ensure that the PCB layout and routing are designed to minimize radiation and susceptibility to external interference.
