The sensor is not reverse polarity protected. Incorrect applications of excitation voltage or ground to the wrong pin can cause electrical failure. Application of supply voltage above the maximum can cause electrical failure. February 2009 / 609 Capacitor 220 nF required between +Vs and GND and 15 nF between Vout and GND. It is important to place the capacitors as close to the pins as possible! Pins 4, 5, 6, 7 and 8 are internal device connections and should not be connected for any reason! 1/5 www.sensortechnics.com ASDX Series A-grade Signal conditioned high precision pressure transducers PRESSURE RANGES SPECIFICATIONS (VS = 5.0 VDC, TA = 25°C) Part number Pressure range Burst pressure1 30 Sensitivity (typ.)

If maximum burst pressure is exceeded, even momentarily, the package may leak or burst, or the pressure sensing die may fracture. 2. Full Scale Span (FSS) is the algebraic difference between the output signal for the highest and lowest specified pressure. Span is ratiometric to the supply voltage. 3. Total accuracy is the combined error of offset and span calibration, linearity, pressure hysteresis and temperature effects. Linearity is the measured deviation based on a straight line. Hysteresis is the maximum output difference at any point within the operating pressure range for increasing and decreasing pressure. Calibration errors include the deviation of offset and full scale from nominal values. 4. Delay time between sampling and signal change at the output. 5. The smallest change in the output voltage, given any change in pressure.
