Software specifications based on MPXA4250A hardware specifications are as follows.
【 H-CMP Architecture 】
The H-CMP Architecture of this product is shown in the figure below.
S-CMP | Pressure | y |
C-CMP | Sensor supply voltage Transformation factor | Vdd Ktc |
M-CMP | Analog input | ai |

【 Sensor Property Conversion 】
Voltage pressure conversion type: Pressure = ( Vout + Vdd ×0.04[V] ) / ( Vdd × 0.004[V/kPa] )

Maximum pressure | iPhysics_max | 250.0 | [kPa] | |
Minimum pressure | iPhysics_min | 20.0 | [kPa] | |
Maximum voltage | iVout_max | 250[kPa]×0.004×Vdd – Vdd×0.04[V] | [V] | |
Minimum voltage | iVout_min | 20[kPa]×0.004×Vdd – Vdd×0.04[V] | [V] |
