ASDX Series Silicon
Pressure Sensors
DESCRIPTION
The ASDX Series is a Silicon Pressure Sensor offering either
an I2C or SPI digital interface for reading pressure over the
specified full scale pressure span and temperature range.
The ASDX is fully calibrated and temperature compensated for
sensor offset, sensitivity, temperature effects and non-linearity
using an on-board Application Specific Integrated Circuit
(ASIC). Calibrated output values for pressure are updated at
approximately 1 kHz.
The standard ASDX is calibrated over the temperature range
of 0 °C to 85 °C [32 °F to 185 °F]. The sensor is characterized
for operation from a single power supply of either 3.3 Vdc or
5.0 Vdc.
FEATURES
Output options: I2C- or SPI-compatible 12-bit digital
Precision ASIC conditioning and temperature
compensated over 0 °C to 85 °C [32 °F to 185 °F]
temperature range
Low operating voltage
Absolute, differential and gage types
Pressure ranges from 10 inches H2O to 100 psi
Standard calibrations in inches H2O, cm H20, psi, mbar,
bar, kPa
Total error band of ±2.0% of full scale span maximum
RoHS compliant
These sensors are available to measure absolute, differential
and gage pressures. The absolute versions have an internal
vacuum reference and an output value proportional to absolute
pressure. Differential versions allow application of pressure to
either side of the sensing diaphragm. Gage versions are
referenced to atmospheric pressure and provide an output
proportional to pressure variations from atmosphere.
The ASDX Series sensors are intended for use with non-
corrosive, non-ionic working fluids such as air and dry gases.
They are designed and manufactured according to standards
in ISO 9001.
POTENTIAL APPLICATIONS
