where
- DATA_OUT = Data thas is available to read using the I2C Interface
- DAC = Digitally compensated value at the input of the DAC
- hx, gx, nx and mx are TC and NL compensation coefficients programmed in EEPROM
- P is pressure
- T is temperature
DAC = DATA_OUT / 1024 in 24-bit mode, or
DAC = DATA_OUT / 4 in 16-bit mode
