is calculated from best fit line to linear input signal range containing 21 pcs analysis points.

Note 2. VDD is stepped from 1.8V to 3.6V and VDD sensitivity in %FS/V calculated as

Note 3. 48 bits out of 512 bits are reserved for internal EEPROM oscillator and clock oscillator trimming, temperature and pressure

measurement gain and offset configurations and sensor resistance trimming. The remaining 464 bits can be freely used for storing calibration

coefficients and other data.

Note 4. There should be at least a 13ms delay after each EEPROM write since EEPROM programming can take up to 13ms.

Note 5. Data retention values apply when extended EEPROM tests are done. Please contact Micro Analog Systems Oy if the data retention

values here need to be guaranteed by comprehensive EEPROM testing.
