(Typical)
The MPX2053 series devices are silicon piezoresistive pressure sensors
that provide a highly accurate and linear voltage output directly proportional to the
applied pressure. A single, monolithic silicon diaphragm with the strain gauge and
an integrated thin-film resistor network. Precise span and offset calibration with
temperature compensation are achieved by laser trimming.

1. 1.0 kPa (kiloPascal) equals 0.145 psi.
2. Device is ratiometric within this specified excitation range. Operating the device above the specified excitation range may induce additional
error due to device self-heating.
3. Full Scale Span (VFSS) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the
minimum rated pressure.
4. Offset (Voff) is defined as the output voltage at the minimum rated pressure.
5. Response Time is defined as the time for the incremental change in the output to go from 10% to 90% of its final value when subjected to a
specified step change in pressure.
6. Offset stability is the product's output deviation when subjected to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test.

Figure 1. Temperature Compensated Pressure Sensor Schematic
Voltage Output versus Applied Differential Pressure
The differential voltage output of the sensor is directly
proportional to the differential pressure applied.
The output voltage of the differential or gauge sensor
increases with increasing pressure applied to the pressure
side relative to the vacuum side. Similarly, output voltage
increases as increasing vacuum is applied to the vacuum
side relative to the pressure side.
On-Chip Temperature Compensation and Calibration
Figure 2 shows the minimum, maximum and typical output
characteristics of the MPX2053 series at 25C. The output is
directly proportional to the differential pressure and is
essentially a straight line.

LINEARITY
Linearity refers to how well a transducer's output follows
the equation: Vout = Voff + sensitivity x P over the operating
pressure range. There are two basic methods for calculating
nonlinearity: (1) end point straight line fit (see Figure 3) or
(2) a least squares best line fit. While a least squares fit gives
the “best case” linearity error (lower numerical value), the
calculations required are burdensome.
Conversely, an end point fit will give the “worst case” error
(often more desirable in error budget calculations) and the
calculations are more straightforward for the user. The
specified pressure sensor linearities are based on the end
point straight line method measured at the midrange
pressure.
