MPR Series—Compact, High Accuracy, Compensated/Amplified
32332628
Datasheet
Issue D
DESCRIPTION
The MPR Series is a very small piezoresistive silicon pressure
sensor offering a digital output for reading pressure over the
specified full scale pressure span and temperature range. It
is calibrated and compensated over a specific temperature
range for sensor offset, sensitivity, temperature effects,
and non-linearity using an on-board Application Specific
Integrated Circuit (ASIC). This product is designed to meet
the requirements of higher volume medical (consumer and
non-consumer) devices, commercial appliance, and industrial/
HVAC applications.

and testing
DIFFERENTIATION
• Application-specific design addresses various application
needs and challenges.
• Digital output: Plug and play feature enables ease of
implementation and system level connectivity.
• Total Error Band: Provides true performance over the
compensated temperature range, which minimizes the
need to test and calibrate every sensor, thereby potentially
reducing manufacturing cost; improves sensor accuracy and
offers ease of sensor interchangeability due to minimal part-
to-part variation. (See Figure 1.)
VALUE TO CUSTOMERS
• Very small form factor: Enables portability by addressing
weight, size, and space restrictions; occupies less area on the
PCB.
• Wide pressure ranges simplify use.
• Enhances performance: Output accelerates performance
through reduced conversion requirements and direct
interface to microprocessors.
• Value solution: Cost-effective, higher volume solution with
configurable options.
• Meets IPC/JEDEC J-STD-020D.1 Moisture Sensitivity Level
1 requirements: Allows avoidance of thermal and mechanical
damage during solder reflow attachment and/or repair that
lesser rated sensors may incur; allows unlimited floor life
when stored as specified (simplifying storage and reducing
scrap); eliminates lengthy bakes prior to reflow, and allows
for lean manufacturing due to stability and usability shortly
after reflow.
• Low power/energy efficient: Reduces system power
requirements and enables extended battery life.
POTENTIAL APPLICATIONS
• Consumer medical: Non-invasive blood pressure monitoring,
negative-pressure wound therapy, breast pumps, mobile
oxygen concentrators, airflow monitors, CPAP water tanks,
and medical wearables
• Non-consumer medical: Invasive blood pressure monitors,
ambulatory blood pressure measurement
• Industrial: Air braking systems, gas and water meters
• Consumer: Coffee machines, humidifiers, air beds, washing
machines, dishwashers

MicroPressure Board Mount Pressure Sensors,
MPR Series
Figure 1. TEB Components for the MPR Series
Total Error Band (TEB) is a single specification that includes
the major sources of sensor error. TEB should not be
confused with accuracy, which is actually a component of
TEB. TEB is the worst error that the sensor could experience.
Honeywell uses the TEB specification in its datasheet
because it is the most comprehensive measurement of
a sensor’s true accuracy. Honeywell also provides the
accuracy specification in order to provide a common
comparison with competitors’ literature that does not use
the TEB specification.
Many competitors do not use TEB—they simply specify
the accuracy of their device. Their accuracy specification,
however, may exclude certain parameters. On their
datasheet, the errors are listed individually. When combined,
the total error (or what would be TEB) could be significant.

Ratiometricity of the sensor (the ability of the device output to scale to the supply voltage):
Achieved within the specified
operating voltage.

The sensor is not reverse polarity protected. Incorrect application of supply voltage or ground to the wrong pin may cause
electrical failure.

Operating temperature range:
The temperature range over which the sensor will produce an output proportional to pressure.

Compensated temperature range:
The temperature range over which the sensor will produce an output proportional to pressure
within the specified performance limits (Total Error Band).
5
Accuracy:
The maximum deviation in output from a Best Fit Straight Line (BFSL) fitted to the output measured over the pressure
range. Includes all errors due to pressure non-linearity, pressure hysteresis, and non-repeatability.
6
Full Scale Span (FSS):
The algebraic difference between the output signal measured at the maximum (Pmax.) and minimum
(Pmin.) limits of the pressure range. (See Figure 2 for pressure ranges.)
