Product details
Overview
MPX2202AP from Freescale Semiconductor is an absolute pressure sensor IC with on-chip temperature compensation, delivering a ratiometric 40 mV full-scale output over 0–200 kPa (0–29 psi) at 10 V supply. It features ±0.5%VFSS linearity, ±0.1%VFSS pressure hysteresis, and operates across –40°C to +125°C. Used in medical diagnostics and barometric sensing where stable zero-point reference is critical.
For engineers reviewing the MPX2202AP datasheet, MPX2202AP pinout, MPX2202AP application, or MPX2202AP equivalent, this page provides verified package mapping (Case 344B-01), calibrated offset range (–2.0 to +2.0 mV), temperature-compensated span stability, and direct alternatives for absolute-pressure transduction in industrial and portable systems.
Technical Context
The MPX2202AP integrates a monolithic silicon diaphragm with piezoresistive strain gauges and thin-film resistor networks laser-trimmed for precise span and offset calibration. Its internal circuitry includes on-chip temperature compensation circuitry referenced to 25°C, enabling stable operation from 0°C to +85°C with TcSpan ≤ ±2.0%VFSS and TcOffset ≤ ±1.0 mV.
As an absolute-pressure sensor, it contains a sealed vacuum reference cavity (P2 side), producing output voltage that decreases under vacuum applied to the P1 port. The device is ratiometric-output scales linearly with supply voltage-and exhibits 1.0 ms response time (10% to 90%) with 20 ms warm-up stabilization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–200 kPa absolute; enables barometric measurement up to ~10,000 m altitude |
| Full Scale Span | 38.5–41.5 mV at VS = 10 Vdc; defines usable analog output swing for ADC interface |
| Offset Voltage | –2.0 to +2.0 mV at min pressure; sets zero-pressure baseline for calibration-critical systems |
| Linearity Error | ±1.0%VFSS (end-point method); determines maximum nonlinearity-induced error across full scale |
| Supply Voltage | 10 Vdc typical, 16 Vdc max; higher excitation increases output but risks self-heating error |
| Response Time | 1.0 ms (10%–90%); supports dynamic pressure monitoring in pump/motor control loops |
| Operating Temp | –40°C to +125°C ambient; validated for automotive under-hood and industrial environments |
Pinout & Package
MPX2202AP uses the Unibody Package Case 344B-01: hermetically sealed stainless-steel cap with silicone-gel-isolated die, 4-pin lead frame, and port-attached P1 side identification per Table 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for both supply and output; must be low-impedance to minimize offset drift |
| 2 | +VOUT | Positive differential output terminal; delivers voltage proportional to absolute pressure minus vacuum reference |
| 3 | VS | Supply input (10 Vdc typical); output scales ratiometrically-critical for supply-referenced ADCs |
| 4 | –VOUT | Negative differential output terminal; completes Wheatstone bridge output path; tied to GND in single-ended use |
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 most applications |
| Laser-trimmed calibration | Factory-set span and offset; reduces system-level calibration effort and improves batch consistency |
| Ratiometric output | Output voltage scales directly with VS; enables high-accuracy measurement using same supply for sensor and ADC reference |
| Vacuum-referenced absolute sensing | Internal sealed vacuum cavity (P2); provides true atmospheric or altitude-referenced pressure without external reference |
| Hermetic Unibody packaging | Stainless-steel cap with silicone gel isolation; ensures long-term reliability in humid or chemically aggressive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure transduction applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX2202A | Same Unibody Case 344 package, identical 0–200 kPa absolute range and 40 mV FS, but marked without /GP suffix; no documented difference in calibration or test screening | No functional distinction in datasheet; used interchangeably in legacy designs where /GP marking not required for traceability | Select MPX2202A only if RoHS compliance or tape-and-reel packaging is not mandated; MPX2202AP/GP includes GP suffix indicating green-process compliance |
| MPXM2202A | MPAK package (Case 1320-02), same 0–200 kPa absolute range and 40 mV FS, but different pinout (GND/VOUT+/VS/VOUT– vs. GND/+VOUT/VS/–VOUT) and smaller footprint | Suitable for space-constrained PCBs; requires layout revision due to different mechanical outline and port orientation | Choose MPXM2202A when board area is limited and rework of mounting footprint is acceptable; verify port alignment matches system hose/barb interface |
Compared with MPX2202AP, MPX2202A offers identical performance in a functionally equivalent package but lacks explicit green-process marking, while MPXM2202A provides the same sensing capability in a surface-mount MPAK variant-requiring PCB redesign but enabling automated assembly and higher density layouts.

FAQ
What is the pressure reference type of the MPX2202AP?
The MPX2202AP is an absolute pressure sensor with an internal sealed vacuum reference cavity on the P2 side. This means its output voltage corresponds to pressure relative to perfect vacuum-not ambient atmospheric pressure-making it suitable for barometric and altimetric applications where a fixed reference is essential. The MPX2202AP datasheet confirms this configuration in the Ordering Information table and Figure 1 schematic.
Does the MPX2202AP require external temperature compensation?
No, the MPX2202AP does not require external temperature compensation. It integrates on-chip thin-film resistor networks and laser-trimmed calibration circuitry that compensate for temperature effects on both full-scale span (TCVFSS ≤ ±2.0%VFSS) and offset (TCVoff ≤ ±1.0 mV) across 0°C to +85°C. This is explicitly stated in the Features section and Operating Characteristics table of the MPX2202AP datasheet.
What is the meaning of the /GP suffix in MPX2202AP/GP?
The /GP suffix in MPX2202AP/GP indicates Green Process compliance-meaning the device meets Freescale's environmental standards for halogen-free materials and lead-free termination finishes. It is not a functional variant; electrical and mechanical specifications match the base MPX2202AP. The /GP marking appears in the ordering row and is confirmed in Freescale's packaging documentation for Case 344B-01.
Can the MPX2202AP be used in differential pressure applications?
No, the MPX2202AP is configured exclusively for absolute pressure measurement and cannot be used for differential pressure sensing. Its internal vacuum reference (P2 side) is sealed and inaccessible; applying pressure to both ports would damage the device or yield invalid output. For differential applications, Freescale specifies the MPX2202DP (Case 344C-01) or MPX2202GP (gauge variant), as shown in the Ordering Information table.
What is the recommended supply voltage range for stable operation of the MPX2202AP?
The MPX2202AP is specified for stable operation with a supply voltage of 10 Vdc (typical), and rated from 0 V to 16 Vdc maximum. Operating above 10 Vdc may induce self-heating errors, as noted in Footnote 2 of the Operating Characteristics table. For optimal accuracy and minimal thermal drift, maintain VS at 10 Vdc ±0.1 V using a low-noise, well-regulated source.
