• Enhanced Dual Serial Interface Mode
Features
The Digital Output pressure sensors are based upon a proprietary surface mapping technology to produce a fully digital
output that virtually eliminates all repeatable errors over temperature and pressure. This series provides a 12 bit digital
serial output (14 bit in High Resolution Mode) with superior offset, span and linearity characteristics. The output is SPI and
MICROWIRE/PLUS
®
compatible as well as fully compatible with the All Sensors GA142 Series sensors.
In addition to synchronous communications, the Digital Output pressure sensors incorporates a bi-directional, TTL level,
asynchronous serial interfaces mode (hardware selectable 9,600 or 19,200 baud). This mode includes a command set that
allows the host to interrogate the sensor for model information, pressure range, serial number, pressure units and
conversion factor. The command set also allows the host to select a high resolution output mode, make minor adjustments
to offset and has an addressable feature that alows multiple sensors to be tied to the same interface buss.
This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like. All signals
are 5V TTL/CMOS compatible.

Synchronous Communications
Typical synchronous communications
configuration (compatible with All
Sensors GA142 Series Digital Output
Sensors).
Typical Configurations
Asynchronous Communications
Typical asynchronous communications
configuration. The Mode pin is
interrogated at power up and if tied
low, will cause the sensor to enter
asynchronous communications mode.
This mode supports multiple sensors by
addressable commands. The Convert/
BR pin then serves to select one of two
available baud rates.

Performance Characteristics for 5 PSI-D-DO through 100 PSI-x-DO
Specification Notes
NOTE 1: UNLESS OTHERWISE SPECIFIED, ALL PARAMETERS ARE MEASURED AT 5.0 VOLT SUPPLY, POSITIVE PRESSURE APPLIED TO PORT B.
NOTE 2: THE DIGITAL OUTPUT IS A 16 BIT SIGNED BINARY OUTPUT IN A TWO’S COMPLIMENT FORMAT. THE APPLIED PRESSURE IS COMPUTED USING THE PRESSURE
CONVERSION TABLE (BELOW). THE MODE COLUMN IDENTIFIES THE RESOLUTION OPERATING MODE OF THE DEVICE (A = STANDARD RESOLUTION, B =
H
IGH RESOLUTION). FSO AND UNITS ARE SHOWN FOR EACH MODEL.
NOTE 3: SHIFT IS WITHIN THE FIRST HOUR OF EXCITATION APPLIED TO THE DEVICE.
NOTE 4: DIGITAL SPAN IS DEPENDENT ON THE RESOLUTION OPERATING MODE. REFER TO THE DIGITAL SPAN TABLE (BELOW) TO IDENTIFY THE DIGITAL SPAN OF THE
SPECIFIC
MODEL. IN THE EVENT OF AN OVER-PRESSURE OR UNDER-PRESSURE CONDITION, THE DIGITAL OUTPUT WILL ONE COUNT HIGHER OR ONE COUNT
LOWER
(RESPECTIVELY) TO THE LISTED DIGITAL SPAN TO INDICATE THE CONDITION.
NOTE 5: OVERALL ACCURACY INCLUDES THE COMBINED EFFECTS OF OFFSET AND SPAN SHIFTS OVER TEMPERATURE, LINEARITY, HYSTERESIS, AND OFFSET AND SPAN
CALIBRATION
.

interface circuit for proper voltage level compatibility.)
