A symmetrical layout with a central ground plane and minimal signal trace length is recommended. STMicroelectronics provides a reference design in the application note AN5271.
Calibration involves applying a known pressure and adjusting the internal compensation registers. STMicroelectronics provides a calibration procedure in the application note AN5271.
The ILPS22QSTR is rated for operation from -40°C to 125°C, but the accuracy and stability of the pressure readings may degrade above 85°C.
The ILPS22QSTR is not designed for use in humid or wet environments. It's essential to ensure the device is properly sealed and protected from moisture to maintain its accuracy and reliability.
The ILPS22QSTR outputs 24-bit pressure data in a 2's complement format. The data should be processed and compensated according to the application note AN5271 to obtain accurate pressure readings.
