The system uses the +5 V supply, and the crystal frequency is 2MHz. R1 and R2 form the power divider, and the analog ground (AGND) is on the midpoint of the power supply. C is the power supply decoupling capacitor. Host can use PC, and the host firstly tests MAX1460 and receives 12-bit parallel data output by MAX1460, then it moves out the testing system, and MAX1460 and the sensor form a high-precision intelligent pressure monitoring system, and the conversion rate is 15 times / sec, the measurement error is less than ± 0.1%. In the Figure, the FSO is the full-scale, OFFSET is the disorder, γ indicates the relative error at full scale.
