FEATURES
- Absolute, gage or differential pressure
- Precision ASIC conditioning
- Temperature compensated GENERAL DESCRIPTION The amplified ASDX offers a high level (4.0 V span) output on a very cost- effective basis. This family is fully calibrated and temperature compensated using an on-board ASIC. These sensors are intended for use with non-corrosive, non-ionic working fluids such as air and dry gases. Devices are available to measure absolute, differential, and gage pressures from 1 to 100 psi. The absolute devices have an internal vacuum reference and an output voltage proportional to absolute pressure. Differential devices allow application of pressure to either side of the sensing diaphragm and can be used for gage or differential measurements. All ASDX devices are accurate to within ±2.0 %FSS. The devices are characterized for operation from a single 5 V supply. The sensor is designed and manufactured according to standards laid down in ISO 9001.
APPLICATIONS
- Medical instrumentation
- Barometry
- HVAC controls
- Pneumatic controls ELECTRICAL CONNECTION Note: 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!

Signal conditioned pressure transducers 4/6February 2009 / 530 www.sensortechnics.com TOTAL ACCURACY (-20 to +105°C) Specification notes: 1. 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 from 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. -20 0 20 40 60 85 105 Temperature (°C) Total accuracy (%FSS) -1.0 -2.0 -3.0 3.0 2.0 1.0
