Posted on September 10, 2014 at 19:17Greetings -The LIS3DSH spec sheet says: ''Land pattern and soldering recommendations are available at www.st.com.''So far, I've not been able to find the info. Could someone please point me in a useful direction?...

characteristics of LPS331AP - Temperature Sensing

Posted on May 22, 2014 at 09:08Is there more detailed spec on the temperature sensing of this part? In the data sheet it states +/- 2C from 0-80C. Is there a range where it is tighter?We are finding that room temp (~25C) we are on the high end +1.4C...
