Pcomp = a0+(b1+c11*Padc+c12*Tadc)*Padc+(b2+c22*Tadc)*Tadc
Where: Padc is the 10-bit pressure output of the MPL115A ADC, Tadc is the 10-bit temperature output of the MPL115A ADC, a0 is the pressure offset coefficient, b1 is the pressure sensitivity coefficient, c11 is the pressure linearity (2nd order) coefficient, c12 is the coefficient for temperature sensitivity coefficient (TCS), b2 is the 1st order temperature offset coefficient (TCO), c22 is the 2nd order temperature offset coefficient.
