Product details
Overview
MPX2202ASX 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 uses a monolithic silicon piezoresistive diaphragm with laser-trimmed thin-film resistor network for precision span/offset calibration. Designed for medical diagnostics and barometric sensing where stable zero-pressure reference is critical.
For engineers reviewing the MPX2202ASX datasheet, MPX2202ASX pinout, MPX2202ASX application, or MPX2202ASX equivalent, this page provides verified technical context, package-specific pin mapping, real-world use scenarios, and validated alternative options for pressure-sensing subsystems requiring ±1.0 mV offset and 0.2 mV/kPa sensitivity.
Technical Context
The MPX2202ASX integrates a vacuum-referenced silicon diaphragm with on-die temperature compensation circuitry, enabling stable operation across –40°C to +125°C. Its ratiometric output ensures proportional response to supply voltage variations, and its unibody Case 344F-01 package isolates the die with silicone gel while exposing the P1 port for absolute pressure measurement.
It delivers end-point linearity of ±1.0% VFSS over 0–200 kPa, with pressure hysteresis ≤±0.1% VFSS and offset stability of ±0.5% VFSS after 1000-hour pulsed pressure/temperature cycling. Input impedance is 1–2.5 kΩ; output impedance is 1.4–3.0 kΩ; response time is 1.0 ms (10%–90%).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–200 kPa absolute - defines full-scale operating envelope with built-in vacuum reference |
| Full Scale Span | 40 mV typical at VS = 10 V - enables direct ADC interfacing without amplification in many 12-bit+ systems |
| Offset Voltage | ±2.0 mV at min pressure - sets baseline output error budget for zero-pressure calibration |
| Sensitivity | 0.2 mV/kPa - linear transduction coefficient used for pressure-to-voltage conversion |
| Linearity Error | ±1.0% VFSS (end-point method) - worst-case deviation from ideal straight-line transfer function |
| Supply Voltage | 10 V typical, 16 V max - ratiometric behavior holds within this range; exceeding induces self-heating error |
| Operating Temp | –40°C to +125°C - supports industrial and automotive under-hood environments |
Pinout & Package
MPX2202ASX uses the Unibody Package Case 344F-01: 4-pin, through-hole, stainless steel cap with port-attached P1 side identification per Table 3. Dimensions: 29.08 × 17.40 × 8.26 mm (L × W × H), with 0.25 mm seating plane tolerance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Ground | Reference node for output and supply return; must be low-impedance path to minimize noise coupling |
| 2 | +Output | Differential output terminal referenced to Pin 4; outputs 0–40 mV proportional to applied absolute pressure |
| 3 | +Supply | Excitation input (VS); device output scales linearly with this voltage (ratiometric) |
| 4 | –Output | Complementary differential output terminal; used with Pin 2 for noise-rejecting instrumentation amp interface |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Stabilizes full-scale span and offset across –40°C to +85°C, reducing external calibration effort |
| Laser-trimmed resistor network | Enables factory calibration of span and offset to ±2.0 mV offset and ±1.0% VFSS linearity |
| Ratiometric output | Output voltage scales directly with supply voltage, simplifying designs using shared ADC reference |
| Vacuum-referenced absolute configuration | Eliminates need for external vacuum chamber; P1 port connects directly to measured environment |
| Unibody Case 344F-01 packaging | Provides robust mechanical isolation via silicone gel encapsulation and stainless steel cap for long-term reliability |

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 | Same Case 344-15 package; identical electrical specs but lacks explicit "SX" tape-and-reel marking; no port-attached P1 identifier in documentation | Designed for same absolute pressure range but may require manual P1-side verification during assembly | Select MPX2202A only if tape-and-reel delivery is not required and board-level orientation verification is feasible |
| MPXM2202AS | MPAK package (Case 1320A-02); same 0–200 kPa range and 40 mV FS, but higher thermal hysteresis (±0.5% vs ±0.1% VFSS) and different pinout (GND/VOUT–/VS/VOUT+) | Better suited for space-constrained PCBs; requires layout revision due to 4-pin SMT footprint and reversed output polarity | Choose MPXM2202AS when board area is limited and rework of schematic/layout for SMT placement is acceptable |
Compared with MPX2202ASX, MPX2202A offers identical performance but less assembly assurance on port orientation, while MPXM2202AS trades mechanical robustness and hysteresis performance for compact surface-mount integration-making MPX2202ASX optimal for through-hole, high-stability absolute pressure measurement where P1-side consistency is critical.

FAQ
What is the pressure reference type of the MPX2202ASX?
The MPX2202ASX is an absolute pressure sensor with an internal vacuum reference cavity. Its output voltage corresponds to pressure measured relative to perfect vacuum-not ambient or differential pressure. This is confirmed by its designation "A" suffix, Case 344F-01 package with port-attached P1 side, and specification of 0–200 kPa absolute range in Table 1 of the datasheet. The MPX2202ASX does not require external vacuum plumbing.
Does the MPX2202ASX require external signal conditioning?
The MPX2202ASX provides a ratiometric 0–40 mV differential output that typically interfaces directly with a precision instrumentation amplifier or a 24-bit delta-sigma ADC. No external temperature compensation or trimming is needed due to on-chip laser calibration and thin-film resistor network. However, a low-noise, matched gain stage is recommended to resolve sub-millivolt changes-especially given its ±2.0 mV offset and 0.2 mV/kPa sensitivity. The MPX2202ASX output impedance (1.4–3.0 kΩ) must be considered when selecting op-amp input bias current.
What is the meaning of "SX" in MPX2202ASX?
In the MPX2202ASX part number, "SX" denotes tape-and-reel packaging per ordering information table. It shares the same Case 344F-01 unibody package and electrical specifications as MPX2202A, but is supplied in automated assembly-ready format. The "SX" suffix also confirms P1-side identification as "side with port attached" per Table 3, distinguishing it from MPX2202A (Case 344-15) which lacks explicit port-side marking guidance. The MPX2202ASX is not a functional variant-it is a packaging and marking variant of the MPX2202A.
Can the MPX2202ASX be used with supply voltages other than 10 V?
Yes-the MPX2202ASX operates from 10 V (typical) up to 16 V DC, maintaining ratiometric behavior across this range. At 5 V supply, output span reduces to ~20 mV; at 15 V, it rises to ~60 mV. However, operation above 10 V increases self-heating, potentially introducing additional error beyond the specified ±2.0% VFSS TCVFSS. The MPX2202ASX datasheet explicitly warns that excitation beyond the specified range may degrade accuracy. For best stability, use regulated 10 V ±0.1 V with low ripple.
What media compatibility considerations apply to the MPX2202ASX?
The MPX2202ASX is qualified for use with dry air as the pressure medium. Exposure to liquids, corrosive gases, oils, or high-humidity environments may degrade silicone gel encapsulation or corrode the stainless steel cap, leading to long-term drift or failure. Freescale's datasheet states that media other than dry air "may have adverse effects on sensor performance and long term reliability." For non-air applications-including medical gas or industrial fluids-consult NXP's factory for compatibility testing data before deployment. The MPX2202ASX is not rated for direct contact with bodily fluids or aggressive solvents.
