Product details
Overview
MPXM2202AS from NXP Semiconductors (formerly Freescale) is an absolute pressure sensor IC with on-chip temperature compensation, delivering a ratiometric 40 mV full-scale output over 0–200 kPa range at 10 V supply. It integrates a monolithic silicon diaphragm with laser-trimmed thin-film resistor network for precision span/offset calibration. Used in medical diagnostics and barometric sensing where stable low-pressure measurement is required.
For engineers reviewing the MPXM2202AS datasheet, MPXM2202AS pinout, MPXM2202AS application, or MPXM2202AS equivalent, this page provides verified technical context, package mapping to CASE 1320A-02, confirmed pin functions, real-world use value in altimeter and pump control systems, and two validated alternative part numbers with documented functional and packaging differences.
Technical Context
The MPXM2202AS implements a piezoresistive sensing element with integrated thin-film temperature compensation circuitry, calibrated across 0°C to +85°C. Its output voltage is strictly ratiometric to supply voltage (VS = 10 Vdc typical), with ±0.5%VFSS offset stability after 1000-hour pulsed pressure/temperature cycling test.
It operates as an absolute pressure transducer using an internal vacuum reference cavity, producing a monotonic 0–40 mV output proportional to applied pressure from 0 to 200 kPa. Input impedance is 1000–2500 Ω; response time is 1.0 ms (10%–90%), and warm-up settles within 20 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–200 kPa absolute - supports barometric and low-range industrial pressure monitoring without external reference. |
| Full Scale Output | 40 mV typical at 10 V supply - enables direct ADC interfacing with 12-bit resolution using common 3.3 V microcontrollers via scaling. |
| Supply Voltage | 10 Vdc nominal, 16 Vdc max - limits self-heating error; operation above 10 V requires thermal validation per design. |
| Linearity Error | ±1.0%VFSS (end-point method) - defines worst-case deviation from ideal linear transfer function across full scale. |
| Temperature Compensation | 0°C to +85°C - ensures calibrated accuracy without external thermistor or software correction in ambient environments. |
| Response Time | 1.0 ms (10%–90%) - suitable for dynamic pressure events such as pump startup or valve actuation detection. |
| Offset Voltage | −2.0 to +2.0 mV at min pressure - sets baseline output level; critical for zero-pressure calibration in closed-system applications. |
Pinout & Package
MPXM2202AS uses the MPAK package (Case 1320A-02), a 4-pin surface-mount ceramic package with ported side for absolute pressure interface. Pin 1 is ground, Pin 2 is −VOUT, Pin 3 is VS, Pin 4 is +VOUT - matching Style 3 configuration per Freescale mechanical drawings.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | GND | Reference ground for both supply and output; must be low-impedance connection to minimize noise coupling into ratiometric signal path. |
| Pin 2 | −VOUT | Low-side output terminal; used with Pin 4 to extract differential voltage - essential for rejecting common-mode supply ripple. |
| Pin 3 | VS | Positive supply input; ratiometric behavior means output scales linearly with VS - requires stable, low-noise 10 V source. |
| Pin 4 | +VOUT | High-side output terminal; forms Wheatstone bridge output pair with Pin 2 - delivers full-scale 40 mV swing referenced to GND. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Eliminates need for external thermistor networks or digital compensation algorithms in 0–85°C operating environments. |
| Laser-trimmed span and offset | Reduces factory calibration effort and enables single-point system-level zero/full-scale adjustment during final test. |
| Ratiometric output | Enables direct connection to microcontroller ADCs powered from same supply - removes requirement for precision voltage references. |
| Monolithic silicon diaphragm | Provides inherent long-term stability and repeatability; avoids bond-wire fatigue or epoxy creep issues found in hybrid assemblies. |
| MPAK surface-mount package | Supports automated PCB assembly and offers hermetic port sealing for reliable pressure interface in compact medical or portable devices. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX2202A | Unibody package (Case 344), through-hole mounting; identical electrical specs but larger footprint and different port orientation. | Used where manual assembly or high-vibration mechanical robustness is prioritized over board space. | Select MPX2202A only when SMT assembly is unavailable or mechanical shock resistance exceeds MPAK requirements. |
| MPXM2202GS | Same MPAK package (Case 1320A-02), gauge configuration - no internal vacuum reference; measures P1–P2 differential pressure. | Requires external venting to atmosphere; unsuitable for true absolute measurements like barometry or sealed-system monitoring. | Choose MPXM2202GS only when measuring relative pressure against ambient, not absolute pressure referenced to vacuum. |
Compared with MPXM2202AS, MPX2202A offers identical performance in a legacy through-hole package requiring more PCB area and manual soldering, while MPXM2202GS shares the same MPAK form factor but lacks the internal vacuum reference needed for absolute pressure applications - making it incompatible for barometric or altimeter use without hardware redesign.

FAQ
What is the pressure type supported by MPXM2202AS?
The MPXM2202AS is an absolute pressure sensor with an internal vacuum reference cavity. It measures pressure relative to absolute zero (vacuum), not ambient atmospheric pressure. This makes MPXM2202AS suitable for barometric sensing, altimeters, and sealed-system monitoring where reference stability is critical. Its specified range is 0–200 kPa absolute, and it cannot be reconfigured for differential or gauge operation.
Does MPXM2202AS require external temperature compensation?
No, MPXM2202AS does not require external temperature compensation. It features on-chip thin-film resistor networks laser-trimmed for temperature compensation across 0°C to +85°C. The datasheet confirms ±2.0%VFSS full-scale span drift and ±1.0 mV offset drift over that range - all implemented internally. External thermistors or software correction algorithms are unnecessary for applications operating within this temperature band.
What is the correct pin configuration for MPXM2202AS?
The MPXM2202AS uses Style 3 pinout per Freescale mechanical drawing CASE 1320A-02: Pin 1 = GND, Pin 2 = −VOUT, Pin 3 = VS, Pin 4 = +VOUT. This configuration forms a differential output pair (Pins 2 and 4) referenced to ground (Pin 1), with supply on Pin 3. Misalignment of this pinout - especially swapping VS and GND - will prevent operation and may damage the device due to reverse biasing of internal circuitry.
Can MPXM2202AS operate with supply voltages other than 10 V?
MPXM2202AS is rated for supply voltages from unspecified minimum up to 16 Vdc, with 10 Vdc as the nominal excitation. Operation above 10 Vdc increases self-heating and may introduce additional error beyond datasheet specifications. At 10 Vdc, full-scale output is 40 mV typical; output remains ratiometric, so at 5 Vdc supply, full-scale drops to ~20 mV. For consistent accuracy and thermal stability, 10 Vdc is strongly recommended as the design point for MPXM2202AS.
Is MPXM2202AS compatible with wet or corrosive media?
No, MPXM2202AS is qualified for use with dry air only, as stated in the Freescale datasheet. Exposure to moisture, oils, solvents, or corrosive gases may degrade silicone gel encapsulation, compromise wire bonds, or contaminate the silicon diaphragm - leading to long-term drift or failure. For non-dry-air applications, consult NXP's media compatibility documentation or select a sensor with appropriate isolation (e.g., stainless steel diaphragm with fluorosilicone seal) - MPXM2202AS itself is not rated for such environments.
