Product Description
bit Output 0.25% Accuracy I2C or SPI Interface Digital differential Pressure Sensor chip for Ventilator
DLHR Series Low Voltage Digital Pressure Sensors
General Description
The DLHR Series Mini Digital Output Sensor is based on All Sensors’ CoBeam2 TM Technology. This reduces package stress susceptibility, resulting in improved overall long term stability and vastly improves the position sensitivity.
The digital interface eases integration of the sensors into a wide range of process control and measurement systems, allowing direct connection to serial communications channels. For battery-powered systems, the sensors can enter very low-power mode between readings to minimize load on the power supply.
These calibrated and compensated sensors provide accurate, stable output over a wide temperature range. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like. A protective parylene coating is optionally available for moisture/harsh media protection.

Specification Notes
note 1: THE SPAN IS THE ALGEBRAIC DIFFERENCE BETWEEN FULL SCALE DECIMAL COUNTS AND THE OFFSET DECIMAL COUNTS.
note 2: TOTAL ERROR BAND ConSISTS OF OFFSET AND SPAN TEMPERATURE AND CALIBRATION ERRORS, LINEARITY AND PRESSURE HYSTERESIS ERRORS, OFFSET
WARM-UP SHIFT, OFFSET POSITION SENSITIVITY AND LONG TERM OFFSET DRIFT ERRORS.
note 3: SHIFT IS RELATIVE TO 25C.
note 4: SHIFT IS WITHIN THE FIRST HOUR OF EXCITATION APPLIED TOTHE DEVICE.
note 5: PARAMETER IS CHARACTERIZED AND NOT 100% TESTED.
note 6: MEASURED AT ONE-HALF FULL SCALE RATED PRESSURE USING BEST STRAIGHT LINE CURVE FIT.
note 7: DATA UPDATe TIME IS EXCLUSIVE OF COMMUNICATIONS, FROM COMMAND RECEIVED TO END OF BUSY STATUS. THIS CAN BE OBSERVED AS EOC PIN
LOW- STATE DURATION.
note 8: AVERAGE CURRENT CAN BE ESTIMATED AS : ICCIdle + (t DU / Reading Interval) * ICCActive). REFER TO FIGURE 2 FOR ACTIVE AND IDLE ConDITIONS OF THE
SENSOR (THE ACTIVE STATE IS WHILE EOC PIN IS LOW).
note 9: THE SENSOR IS CALIBRATED WITH A 3.3V SUPPLY HOWEVER, AN INTERNAL REGULATOR ALLOWS A SUPPLY VOLTAGE OF 1.68V TO 3.6V TO BE USED
WITHOUT AFFECTING THE OVERALL SPECIFICATIONS. THIS ALLOWS DIRECT OPERATION FROM A BATTERY SUPPLY.
