H2O, 0 in to ±10 in H2O
DESCRIPTION
All ASDXL DO sensors are accurate to within ±2.5 % Full
The ASDXL DO Series pressure sensors are fully calibrated
Scale Span (FSS) and are intended for use with non-corrosive,
and temperature compensated with on-board Application
non-ionic working fluids such as air and dry gases. (Contact
Specific Integrated Circuitry (ASIC). This ASDXL DO sensor is
factory for media compatibility on G2/D4 packages.)
in a DIP format (Dual In-line Package) and provides digital
correction of sensor offset, sensitivity, temperature coefficients
2
This series is designed and manufactured in accordance with
and non-linearity. The ASDXL DO Series has 12-bit I C
ISO 9001 standards and is compliant with the WEEE and
compatible protocol interface which allows easy interfacing to
RoHS directives.
most commonly used microcontrollers and microprocessors.
2
The 2-wire I C interface has a Serial Clock Line input (SCL)
and serial digital output data line. The output of the device is a
corrected pressure value in hexadecimal format with 12-bit
accuracy (unsigned) and not ratiometric to the supply voltage.

Notes:
1. If burst pressure is exceeded, even momentarily, the package may leak or the pressure sensing die may fracture.
2. Reference conditions (unless otherwise noted): supply voltage, VS=5.0 ±0.01 Vdc, Ta=25 °C [77 °F].
3. Read operation: Start, Slave Address, R/W =1, Data Byte 1 (MSB), Ackn Bit, Data Byte 2 (LSB). The output is corrected pressure as unsigned
12 bits. Slave Address is F0h. Acknowledge Bit - pull data line LOW, master generates an extra clock pulse for this purpose.
4. Span is the algebraic difference between the output voltage at the specified pressure and the output at zero pressure.
5. Output is non-ratiometric within the supply voltage range (Vs).
6. Output of the device when maximum positive pressure is applied on the backside (P2) or the front side (P1) of the sensing element.
7. Accuracy is the combined errors from offset and span calibration, linearity, pressure hysteresis, and temperature effects. Calibration errors
include the deviation of offset and full scale from nominal values 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 and temperature.
8. Response time for 0 PSI to full scale pressure step change, 10% to 90% rise time.
9. 220 nF capacitor required between +Vs and GND.

ASDXLYYD4ZZ-DO
ASDXLYYG2ZZ-DO
Notes:
1. N/C means no connection. Connecting to ground or other potential may damage sensors.
2. Capacitor 220 nF required between +Vs and GND.
3. The sensor is not reverse polarity protected. Incorrect application of excitation voltage or ground to the wrong pin can cause electrical failure.
Application of supply voltage above the maximum can cause electrical failure.
