Product details
Overview
MPX2102AP from Freescale Semiconductor is a temperature-compensated silicon piezoresistive absolute pressure sensor in Unibody Package (Case 344B), delivering 40 mV full-scale output at 10 V supply across 0–100 kPa range, with ±0.4%VFSS linearity and ±0.1%VFSS pressure hysteresis - used in medical diagnostics, barometers, and vacuum-sensing systems requiring stable analog pressure transduction.
For engineers reviewing the MPX2102AP datasheet, MPX2102AP pinout, MPX2102AP application, or MPX2102AP equivalent, this page provides verified technical context, calibrated performance parameters, package-specific terminal mapping, real-world use scenarios, and validated alternative options for pressure sensing design-in.
Technical Context
The MPX2102AP integrates a monolithic silicon diaphragm with on-chip strain gauge and thin-film resistor network, laser-trimmed for span/offset calibration and temperature compensation over 0°C to +85°C. Its ratiometric output scales linearly with applied absolute pressure relative to internal vacuum reference.
It operates with 10 VDC excitation (range 10–16 VDC), draws 6.0 mA supply current, and exhibits 1.0 ms response time (10%–90%), 20 ms warm-up time, and ±0.5%VFSS offset stability after 1000-hour pulsed pressure/temperature cycling test.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–100 kPa absolute - defines full-scale operating envelope referenced to internal vacuum cavity. |
| Full Scale Span | 40 mV typical at 10 V supply - direct analog output proportional to pressure, enabling simple ADC interfacing without gain staging. |
| Linearity Error | ±0.4%VFSS (end-point method) - ensures ≤0.4 kPa deviation from ideal transfer curve across full scale at 25°C. |
| Offset Voltage | −2.0 to +2.0 mV - output at zero pressure, critical for low-pressure accuracy and system zeroing calibration. |
| Temperature Compensation | 0°C to +85°C - on-chip circuitry minimizes span and offset drift, reducing need for external thermal correction. |
| Response Time | 1.0 ms (10%–90%) - supports dynamic pressure monitoring in fast-cycling applications like pump control or robotics. |
| Supply Voltage | 10–16 VDC - ratiometric operation maintains output proportionality even with supply variation within range. |
Pinout & Package
MPX2102AP uses Unibody Package Case 344B: 4-pin, stainless-steel capped, ported housing with silicone-gel-isolated die; dimensions 29.08 × 17.40 × 8.26 mm (L × W × H), seating plane defined per ANSI Y14.5M-1982.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Ground | Reference node for output and supply return; must be low-impedance connection to minimize noise coupling. |
| 2 | + Output (VOUT+) | High-side analog output terminal; delivers voltage proportional to absolute pressure (0–40 mV). |
| 3 | + Supply (VS) | Excitation input; supplies regulated 10–16 VDC to internal Wheatstone bridge and compensation circuitry. |
| 4 | − Output (VOUT−) | Differential output complement; enables true differential readout to reject common-mode noise. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Reduces span and offset drift over 0°C to +85°C, eliminating need for external thermistor networks or software compensation algorithms. |
| Laser-trimmed calibration | Ensures factory-set accuracy for span and offset, enabling plug-and-play integration without user trimming. |
| Unibody absolute configuration | Internal vacuum reference allows direct absolute pressure measurement without external reference port or plumbing. |
| Ratiometric output | Maintains proportional relationship between output voltage and supply voltage, improving system robustness against supply rail fluctuations. |
| Low-pressure hysteresis | ±0.1%VFSS hysteresis ensures repeatable readings during pressure cycling - critical for level detection and barometric trending. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX2102A | Same die, Case 344 (unported stainless cap); no P1 port; requires external pressure conduit. | Used where environmental sealing is prioritized over direct port access; unsuitable for inline mounting. | Select MPX2102A only when mechanical integration demands fully sealed housing and external tubing is acceptable. |
| MPXM2102AS | MPAK package (Case 1320A), same 0–100 kPa absolute range, but higher input impedance (1.5 kΩ min) and different pinout (GND/VOUT−/VS/VOUT+). | Designed for surface-mount assembly and space-constrained PCBs; lacks ported housing, requiring external pressure interface. | Choose MPXM2102AS for automated SMT production and compact layouts, accepting trade-off of added external porting hardware. |
Compared with MPX2102AP, MPX2102A offers identical sensing performance but requires external pressure routing, while MPXM2102AS enables smaller footprint and reflow compatibility at the cost of mechanical integration complexity and altered pin assignment.

FAQ
What is the pressure type and reference configuration of the MPX2102AP?
The MPX2102AP is an absolute pressure sensor with an internal vacuum reference cavity. It measures pressure relative to perfect vacuum, not ambient atmosphere. This configuration is confirmed by its Case 344B packaging, ported on the P1 side, and documentation specifying "Absolute" in the ordering table. The MPX2102AP outputs a voltage that decreases under vacuum applied to the P1 port, consistent with absolute reference behavior. Its full-scale range is 0–100 kPa absolute.
What are the supply voltage requirements and current draw for MPX2102AP?
The MPX2102AP operates with a supply voltage of 10–16 VDC, with 10 VDC being the nominal excitation point for specified performance. At 10 VDC and 25°C, it draws 6.0 mA typical supply current. Operation above 16 VDC is not recommended due to self-heating effects that may increase error. The device is ratiometric, meaning its output voltage scales linearly with supply voltage, preserving measurement accuracy across the valid supply range.
Does MPX2102AP provide differential or single-ended output capability?
The MPX2102AP provides true differential analog output via pins 2 (+VOUT) and 4 (−VOUT), enabling noise-rejecting measurement with instrumentation amplifiers. It does not offer a single-ended output option - the ground-referenced output is not internally available. This differential architecture is integral to its design, as shown in Figure 1 of the datasheet, and supports high common-mode rejection in electrically noisy environments such as motor control or industrial equipment.
What is the temperature compensation range and accuracy impact for MPX2102AP?
The MPX2102AP features on-chip temperature compensation over 0°C to +85°C, covering its specified operating ambient range. Within this range, total error contributions include ±1.0%VFSS TcSpan and ±1.0 mV TcOffset, as documented in Table 1. These values represent worst-case deviations from 25°C baseline performance. The compensation is factory-laser-trimmed and does not require external components or software correction to meet datasheet accuracy specifications across the full compensated range.
Can MPX2102AP be used with media other than dry air?
No - the MPX2102AP's qualification testing and reliability data are based exclusively on dry air as the pressure medium. Freescale explicitly warns that exposure to other media (e.g., liquids, corrosive gases, or humid air) may degrade long-term performance or cause permanent damage. Silicone gel isolation protects the die but does not guarantee chemical compatibility. For non-dry-air applications, users must contact NXP (successor to Freescale) for media compatibility validation before deployment; the MPX2102AP datasheet does not authorize use with alternate media.
