The small form factor and high reliability of on–chip integration make the Motorola pressure sensor a logical and economical choice for the system designer. The MPX4115A/MPXA4115A series piezoresistive transducer is a state–of–the–art, monolithic, signal conditioned, silicon pressure sensor. This sensor combines advanced micromachining techniques, thin film metallization, and bipolar semiconductor 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 sensor chip.

Minimum Pressure Offset(2) @ VS = 5.1 Volts Full Scale Output(3) @ VS = 5.1 Volts Full Scale Span(4) @ VS = 5.1 Volts Accuracy(5) Sensitivity Response Time(6) Output Source Current at Full Scale Output Warm–Up Offset Time(7) Stability(8) NOTES: 1. Device is ratiometric within this specified excitation range. 2. Offset (Voff) is defined as the output voltage at the minimum rated pressure. 3. Full Scale Output (VFSO) is defined as the output voltage at the maximum or full rated pressure. 4. 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. 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: • Linearity: 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°.
