High Temperature Accuracy
Integrated Silicon Pressure Sensor for Measuring Absolute Pressure, On-Chip Signal Conditioned, Temperature Compensated and Calibrated
The MPXA6115A/MPXH6115A ries nsor integrates on-chip, bipolar op amp circuitry and thin film resistor networks to provide a high output signal and temperature compensation. The small form factor and high reliability of on-chip integration make the pressure nsor a logical and economical choice for the system designer.
The MPXA6115A/MPXH6115A ries piezoresistive transducer is a state-of-the-art, monolithic, signal conditioned, silicon pressure nsor. This nsor combines advanced micromachining techniques, thin film metallization, and bipolar miconductor processing to provide an accurate, high level analog output signal that is proportional to applied pressure.
Figure 1 shows a block diagram of the internal circuitry integrated on a pressure nsor chip.Features •Improved Accuracy at High Temperature

1.Device is ratiometric within this specified excitation range.
2.Offt (V off ) is defined as the output voltage at the minimum rated pressure.
3.Full Scale Output (V FSO ) is defined as the output voltage at the maximum or full rated pressure.
french letter4.Full Scale Span (V FSS ) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the minimum rated pressure.
5.Accuracy is the deviation in actual output from nominal output over the entire pressure range and temperature range as a percent of span at 25°C due to all sources of error including the following:•Li
nearity:Output deviation from a straight line relationship with pressure over the specified pressure range.
•Temperature Hysteresis:Output deviation at any temperature within the operating temperature range, after the temperature is cycled to
and from the minimum or maximum operating temperature points, with zero differential pressure applied.
•Pressure Hysteresis:Output deviation at any pressure within the specified range, when this pressure is cycled to and from minimum
or maximum rated pressure at 25°C.
•TcSpan:Output deviation over the temperature range of 0° to 85°C, relative to 25°C.•TcOfft:Output deviation with minimum pressure applied, over the temperature range of 0° to 85°C, relative to 25°C.6.Respon 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.7.Warm-up Time is defined as the time required for the product to meet the specified output
voltage after the pressure has been stabilized.8.Offt Stability is the product's output deviation when subjected to 1000 cycles of Puld Pressure, Temperature Cycling with Bias Test.

Figure 2 illustrates the absolute nsing chip in the basic Super Small Outline chip carrier (Ca 1317).
Figure 3 shows a typical application circuit (output source current operation).
Figure 4 shows the nsor output signal relative to pressure input. Typical minimum and maximum output
curves are shown for operation over 0 to 85×C temperature range. The output will saturate outside of the rated pressure range.
A fluorosilicone gel isolates the die surface and wire bonds from the environment, while allowing the pressure signal to be transmitted to the silicon diaphragm. The MPXA6115A/MPXH6115A ries pressure nsor operating
characteristics, internal reliability and qualification tests are bad on u of dry air as the pressure media. Media other than dry air may have adver effects on nsor performance and long-term reliability. Contact the factory for information regarding media compatibility in your application.
