The pressure test system circuit which is composed of the MAX1460 and the silicon pressure sensor is as shown in the figure. This system uses the +5V power supply, the crystal frequency is 2MHz. The power supply voltage divider is composed of the R1 and R2, the AGND is connected at the midpoint of the power supply. The C is the power-supply decoupling capacitance. The host machine is the PC, the host machine tests the MAX1460 and receives the 12-bit parallel data which is output by the MAX1460, then it moves out the test system, the high precision intelligent pressure detection system is composed of the MAX1460 and the tested sensor, the conversion rate is 15 times/second, the measurement error is less than ±0.1%.
