MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MPXS4100A/D IOT&nentCme-CagplhreiabirptraeatSdtuiergPdenraeClsosCmuoprneednSitseiaontnseeoddr,, The Motorola MPXS4100A series Barometric Absolute Pressure (BAP) sensor for engine control is designed to sense absolute air pressure. Motorola’s BAP sensor 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 Motorola BAP sensor a logical and economical choice for the automotive system designer.

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 minimum specified 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: Span deviation per °C over the temperature range of 0° to 85°C, as a percent of span at 25°C. • TcOffset: Output deviation per °C with minimum pressure applied, over the temperature range of 0° to 85°C. 6. 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. 7. Warm–up Time is defined as the time required for the product to meet the specified output voltage. 8. Offset Stability is the product’s output deviation when subjected to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test. 9. Decoupling circuit shown in Figure 2 required to meet specification. 2 Motorola Sensor Device Data MPXS4100A SENSOR OUTPUT (PIN 4) 50 pF A/D 51 k µ PROCESSOR MPXS4100A SERIES Figure 2.
