Product details
Overview
MPX2100AP from Freescale Semiconductor is an absolute pressure sensor IC with on-chip temperature compensation and laser-trimmed calibration, delivering 40 mV full-scale output at 10 V supply across a 0–100 kPa range. It features ±0.25% linearity (end-point method), ratiometric output, and operates over –40°C to +125°C. Used in barometric sensing and medical diagnostics where stable, calibrated analog pressure signals are required.
For engineers reviewing the MPX2100AP datasheet, MPX2100AP pinout, MPX2100AP application, or MPX2100AP equivalent, this page provides verified technical context, package-validated pin functions, real-world use scenarios, and two confirmed alternative parts for pressure-sensing designs requiring absolute configuration, unibody packaging, and millivolt-level analog output.
Technical Context
The MPX2100AP integrates a monolithic silicon piezoresistive diaphragm with thin-film resistor networks for strain measurement and on-chip temperature compensation circuitry. Its output voltage is directly proportional to applied absolute pressure relative to internal vacuum reference, with offset and span trimmed via laser calibration.
It operates ratiometrically to supply voltage (10 V typical, up to 16 V max), exhibits 1.0 ms response time (10–90%), and maintains ±0.5% VFSS offset stability after 1000-hour pulsed pressure/temperature cycling. Input and output impedances are 1–2.5 kΩ and 1.4–3 kΩ respectively, enabling direct interface with instrumentation amplifiers or ADC front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–100 kPa absolute; enables barometric measurement (≈0–14.5 psi) without external reference. |
| Full Scale Span | 40 mV typical at 10 V supply; provides high signal-to-noise ratio for low-gain analog signal chains. |
| Linearity Error | ±0.25% VFSS (end-point method); supports precision pressure measurement without software linearization in many applications. |
| Temperature Range | –40°C to +125°C operating; suitable for under-hood automotive, industrial enclosures, and portable medical devices. |
| Supply Voltage | 10 V typical, 16 V max; ratiometric behavior ensures output scaling tracks supply variations, simplifying power rail design. |
| Response Time | 1.0 ms (10–90%); adequate for dynamic pressure monitoring in pump control and robotics. |
| Offset Voltage | ±2.0 mV at minimum rated pressure; low initial offset reduces need for null adjustment in production calibration. |
Pinout & Package
MPX2100AP uses Case 344B-01 - a unibody ceramic package with port-attached side identification (P1 side), stainless steel cap, and silicone gel isolation. Dimensions: 29.08–29.85 mm × 17.40–18.16 mm × 7.75–8.26 mm (L×W×H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for both supply and output; must be low-impedance to minimize common-mode error. |
| 2 | +VOUT | Positive differential output terminal; delivers voltage proportional to absolute pressure above vacuum reference. |
| 3 | VS | Positive supply input (10 V typical); powers sensing element and compensation circuitry; ratiometric output scales with VS. |
| 4 | –VOUT | Negative differential output terminal; completes Wheatstone bridge output path; referenced to GND. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Validated over 0°C to +85°C; eliminates need for external thermistor or digital correction in mid-range ambient applications. |
| Laser-trimmed span and offset | Reduces factory calibration effort; achieves ±0.25% linearity and ±2.0 mV offset without post-packaging trimming. |
| Ratiometric output | Output scales linearly with supply voltage; allows use of same regulator for sensor and downstream ADC, improving system accuracy. |
| Absolute pressure configuration | Internal vacuum reference enables true atmospheric or altitude-referenced measurements without external venting or plumbing. |
| Unibody ceramic package (Case 344B-01) | Robust mechanical construction with silicone gel protection; withstands humidity, vibration, and thermal cycling in harsh environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX2100ASX | Same die, Case 344F-01 package with port-attached side identification; identical electrical specs and calibration. | Designed for surface-mount assembly with different mechanical mounting geometry; not drop-in compatible due to distinct footprint and port orientation. | Select MPX2100ASX only when board layout accommodates Case 344F-01's 27.43–28.45 mm × 18.80–19.30 mm outline and side-port configuration. |
| MPX5100AP | Successor generation with integrated signal conditioning; 0–100 kPa range, but outputs 0.2–4.7 V (not ratiometric mV) and requires 4.75–5.25 V supply. | Replaces discrete amplifier stages; incompatible with legacy MPX2100AP analog front-ends due to different output format and supply requirements. | Choose MPX5100AP for new designs needing amplified output and reduced external components; avoid for drop-in replacement of MPX2100AP. |
Compared with MPX2100ASX, MPX2100AP offers identical sensing performance but differs in mechanical mounting and port location-requiring PCB redesign. Compared with MPX5100AP, MPX2100AP retains legacy-compatible millivolt output and wide-supply operation but lacks onboard amplification, making it suitable for designs with existing precision gain stages.

FAQ
What is the pressure type and reference configuration of the MPX2100AP?
The MPX2100AP is an absolute pressure sensor with an internal vacuum reference cavity. It measures pressure relative to perfect vacuum-not ambient air or a second port-making it suitable for barometric and altitude-sensing applications. This configuration is confirmed by Freescale's ordering table (MPX2100AP = Absolute, Case 344B) and the "P1 side" designation as the port-attached side with internal vacuum reference.
Does the MPX2100AP require external amplification to interface with a standard microcontroller ADC?
Yes, the MPX2100AP outputs a low-level ratiometric signal of approximately 40 mV full scale, which typically requires amplification (e.g., 50–100× gain) to match the input range of most 10–16 bit microcontroller ADCs. Its output impedance (1.4–3 kΩ) and differential nature also necessitate an instrumentation amplifier or matched resistor network for optimal common-mode rejection and noise immunity.
What is the maximum supply voltage rating for the MPX2100AP, and what happens if exceeded?
The MPX2100AP has a maximum supply voltage of 16 Vdc, per Freescale's Operating Characteristics table. Exceeding this limit may cause permanent damage or increased error due to self-heating, as explicitly noted in the datasheet. Operation at 10 Vdc is recommended for optimal linearity and temperature stability; higher voltages increase power dissipation without improving sensitivity.
Is the MPX2100AP RoHS compliant and lead-free?
The MPX2100AP/GP variant (as indicated in the ordering row) denotes green packaging per Freescale's nomenclature-meaning lead-free and RoHS-compliant. This is consistent with Freescale's 2008-era "GP" suffix convention (e.g., MPX2100AP/GP), aligned with EU RoHS Directive 2002/95/EC compliance requirements for industrial components shipped after July 1, 2006.
Can the MPX2100AP be used with wet media such as water or oil?
No-the MPX2100AP is qualified only for dry air as the pressure medium. Freescale explicitly states that "media other than dry air may have adverse effects on sensor performance and long term reliability." For liquid or corrosive gas applications, consult NXP (ex-Freescale) for media-compatible alternatives or custom qualification; standard MPX2100AP units lack protective coatings or seals for direct fluid contact.
