... Miniature I C Digital Barometer The MPL115A2 is an absolute pressure sensor with digital output for low cost applications. A miniature 1.2 mm LGA package ideally suits it for portable electronics and space constrained applications. Low current consumptions of 5 μA during Active mode and 1 μA during Shutdown (Sleep) mode target battery and other low-power applications. A wide operating temperature range from -40° ...

... C Outputs: SDA 15 Data Setup Time Addressing MPL115A2 uses 7-bit addressing, does not acknowledge the general call address 0000000. Slave address has been set to 0x60 or 1100000. MPL115A2 2 Conditions Shutdown (SHDN = GND) Standby Average – at one measurement per second -20ºC to 85ºC Typical operating circuit at DC 100 mV p-p 217 Hz square wave plus 100 mV pseudo random noise with 10 MHz bandwidth ...

... Temp Temp Sensor Sensor Compensation The pressure compensation for MPL115A2 is based on a 2-dimensional, second order polynomial. The 10-bit compensated pressure output, Pcomp, is calculated as follows: Pcomp = a0 + (b1 + c11*Padc + c12*Tadc) * Padc + (b2 + c22*Tadc) * Tadc Where: Padc is the 10-bit pressure output of the MPL115A2 ADC, Tadc is the 10-bit temperature output of the MPL115A2 ADC, ...

... For coefficients with less than 16 bits, the lower lsbs are zero. For example, c11 is 11 bits and is stored into 2 bytes as follows: c11 MS byte = c11[10:3] = [c11 b10 c11 LS byte = c11[2:0] & “00000” = [c11 MPL115A2 4 b2 c12 — ...

... MPL115A Pressure Sensor increase the possibility of damage via a foreign object/tool into the small exposed port. The sensor die is sensitive to light exposure. Direct light exposure through the port hole can lead to varied accuracy of pressure measurement. Avoid such exposure to the port during normal operation.
