WARNING
PERSONAL INJURY
DO NOT USE these
products as safety or
emergency stop devices or
in any other application
where failure of the product
could result in personal
injury.
Failure to comply with
these instructions could
result in death or serious
injury.
The ASDX series is an amplified version of Honeywell’s proven performer
and industry leading SDX series sensor. The amplified ASDX sensor’s
footprint is slightly larger than the SDX but it offers a high level output (4.0
Vdc span) on a very cost-effective basis. This series is fully calibrated and
temperature compensated with on-board Application Specific Integrated
Circuitry (ASIC). They are intended for use with non-corrosive, non-ionic
working fluids; such as air and dry gases.
Sensors are available to measure absolute, differential, and gage pressures.
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 gauge or differential measurements.
All ASDX devices are accurate to within ± 2.0 % full scale, designed for
operation from a single 5.0 Vdc supply and are manufactured in accordance
with ISO 9001 standards.

SPECIFICATION NOTES
Note 1: Capacitor 220 nF required between +Vs and GND pin.
Note 2: Pins 4, 5, 6, 7 and 8 are internal device connections and should not be connected to external circuitry or ground.
Note 3: If maximum burst pressure is exceeded, even momentarily, the package may leak or burst, or the pressure sensing die may
fracture.
Note 4: Reference Conditions (unless otherwise noted): Supply voltage, VS=5.0 ± 0.01 Vdc; TA=25 °C [77 °F]. Output is ratiometric within
the supply voltage range (Vs).
Note 5: Span is the algebraic difference between the output voltage at the specified pressure and the output at zero pressure. Span is
ratiometric to the supply voltage.
Note 6: Accuracy is the combined errors 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.
Note 7: Response time for a 0 psi to full-scale pressure step change, 10 % to 90 % rise time.
Note 8: The smallest change in the output voltage, given any change in pressure.
