GENERAL DESCRIPTION
The amplified ASDXL series offers a
high level output (4.0 V or ±2.0 V span
respectively) on a very cost-effective
basis. This family is fully calibrated
and temperature compensated using
an on-board ASIC. The sensors are
intended for use with non-corrosive,
non-ionic working fluids such as air
and dry gases.
The ASDXL10D44R device is
available to measure gage pressure
from 0...10 "H
2
O and offers 4 V span.
APPLICATIONS
· Medical instrumentation
· HVAC controls
· Pneumatic controls
The ASDXL...4D devices are available
to measure differential pressures from
0...±5 "H
2
O (ASDXL05D44D) to
0...±10 "H
2
O (ASDXL10D44D) and
offer ±2.0 V span. Differential devices
allow application of pressure to either
side of the sensing diaphragm and
can be used for gage or differential
measurements.
All ASDXL devices are accurate to
within ±2.5 %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
ISO9001.

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!

Caution!
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.

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.
