Characteristic Symbol Min Max Unit Power Supply Voltage +12 10.75 16 Volts Operating Current ICC 75 mA Full Scale Pressure MPX2010 MPX2050 MPX2100 MPX2200 Pfs 1.5 7.5 15 30 PSI PSI PSI PSI PIN–BY–PIN DESCRIPTION +12: Input power is supplied at the +12 terminal. The minimum operating voltage is 10.75 Vdc and the maximum operating voltage is 16 Vdc. GND: The ground terminal is the power supply return for the system. TP1: Test point 1 is connected to the final op amp stage. It is the voltage that is applied to the microprocessor’s A/D converter. There are two ports on the pressure sensor located at the bottom center of the printed circuit board. The pressure port is on the top left and the vacuum port is on the bottom right of the sensor. – + – + – + + – PD1 2–A2 PD2 2–A3 PD3 2–A3 PD4 2–A3 PD5 2–A3 PD6 2–A3 PD7 2–A3 +12 IN GROUND P1 1N4002 D1 1 µF + C1 U4 78L08 IN OUT GROUND U3 78L05 IN OUT GROUND 1 µF + 0.1 C2 C3 +5 V +8 R12 R13 R14 VRH 2–D4 VRL 2–D4 402 3.32K 1 µF + C5 0.1 C4 CPU_RESET 2–B4 MC34064P–5 +IN GND OUT U2 +5 V +5 V R11 4.7K PD0 2–A2 TP1 +5 V 1N914 4.7K R4 8 10 9 R5 2K R6 2K 14 12 13 U1A U1C U1D U1B 3 2 11 1 976 R9 1K R10 340 R7 R8 23.7 +8 +8 14 23 XDCR1 121 R2 200 R3 6.98K R1 5 6 4 7 +12 V MC33274 D2 +5 V 7 x 47K J1 J2 J3 J4 J5 J6 J7 SENSOR TYPE SELECT SLOPE ADJ.
