Compensated Pressure Sensor
MPX2300DT1
Freescale Semiconductor has developed a high volume, miniature pressure
sensor package which is ideal as a sub-module component or a disposable unit.
The unique concept of the Chip Pak allows great flexibility in system design while
providing an economic solution for the designer. This new chip carrier package
uses Freescale Semiconductor's unique sensor die with its piezoresistive
technology, along with the added feature of on-chip, thin-film temperature
compensation and calibration.

General Description
The MPX2300DT1 pressure sensor has been designed for medical usage by combining the performance of Freescale's shear
stress pressure sensor design and the use of biomedically approved materials. Materials with a proven history in medical
situations have been chosen to provide a sensor that can be used with confidence in applications, such as invasive blood
pressure monitoring. It can be sterilized using ethylene oxide. The portions of the pressure sensor that are required to be
biomedically approved are the rigid housing and the gel coating.
The rigid housing is molded from a white, medical grade polysulfone that has passed extensive biological testing including:
ISO 10993-5:1999, ISO 10993-10:2002, and ISO 10993-11:1993.
A silicone dielectric gel covers the silicon piezoresistive sensing element. The gel is a nontoxic, nonallergenic elastomer system
which meets all USP XX Biological Testing Class V requirements. The properties of the gel allow it to transmit pressure uniformly
to the diaphragm surface, while isolating the internal electrical connections from the corrosive effects of fluids, such as saline
solution. The gel provides electrical isolation sufficient to withstand defibrillation testing, as specified in the proposed Association
for the Advancement of Medical Instrumentation (AAMI) Standard for blood pressure transducers. A biomedically approved
opaque filler in the gel prevents bright operating room lights from affecting the performance of the sensor.

1. Recommended voltage supply: 6 V ± 0.2 V, regulated. Sensor output is ratiometric to the voltage supply. Supply voltages above +10 V may
induce additional error due to device self-heating.
2. Measured at 6.0 VDC excitation for 100 mmHg pressure differential. VFSS and FSS are like terms representing the algebraic difference
between full scale output and zero pressure offset.
3. Maximum deviation from end-point straight line fit at 0 and 200 mmHg.
4. Slope of end-point straight line fit to full scale span at 15 °C and +40 °C relative to +25 °C.
5. Slope of end-point straight line fit to zero pressure offset at 15 °C and +40 °C relative to +25 °C.
6. Offset measurement with respect to the measured sensitivity when a 150 k resistor is connected to VS and VOUT+ output.
7. For a 0 to 300 mmHg pressure step change.
