Product details
Overview
MPX2202A from Freescale Semiconductor is an absolute pressure sensor IC with monolithic silicon piezoresistive sensing element, on-chip temperature compensation (0°C to +85°C), ratiometric 40 mV full-scale output at 10 V supply, and 0–200 kPa (0–29 psi) measurement range - used in barometers, altimeters, and medical diagnostic equipment requiring stable analog pressure transduction.
For engineers reviewing the MPX2202A datasheet, MPX2202A pinout, MPX2202A application, or MPX2202A equivalent, this page delivers verified package mapping (Case 344-15), confirmed terminal roles (GND, +VOUT, VS, –VOUT), calibrated performance parameters (±1.0%VFSS linearity, ±0.5%VFSS offset stability), and real-world use context for embedded pressure-sensing systems.
Technical Context
The MPX2202A integrates a single silicon diaphragm with laser-trimmed strain gauges and thin-film resistor networks for precision span/offset calibration. Its internal circuitry provides ratiometric output scaling relative to supply voltage (VS = 10 Vdc typical), enabling direct ADC interfacing without external gain adjustment.
It features built-in vacuum reference for absolute pressure measurement, with output decreasing under vacuum applied to the P1 port. The device operates across –40°C to +125°C, though full temperature compensation is specified only over 0°C to +85°C per datasheet Table 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–200 kPa absolute - defines full-scale input range with built-in vacuum reference; supports barometric (≈100 kPa) and altimetric (≈30–100 kPa) applications. |
| Full Scale Span | 40 mV typical at VS = 10 V - enables high-resolution analog-to-digital conversion with minimal amplification (e.g., 12-bit ADC resolution ≈ 10 Pa). |
| Supply Voltage | 10 Vdc typical, 16 Vdc max - ratiometric operation ensures output scales linearly with supply; self-heating error increases above 10 V. |
| Linearity Error | ±1.0%VFSS (end-point method) - worst-case deviation from ideal linear transfer function across 0–200 kPa, critical for calibration-critical instrumentation. |
| Offset Voltage | –2.0 to +2.0 mV at min pressure - zero-pressure output tolerance; requires system-level offset nulling or calibration in precision applications. |
| Response Time | 1.0 ms (10% to 90%) - supports dynamic pressure monitoring up to ~350 Hz bandwidth without significant phase lag. |
| Operating Temp | –40°C to +125°C - wide ambient range suitable for industrial enclosures; compensated performance guaranteed only from 0°C to +85°C. |
Pinout & Package
MPX2202A uses the Unibody Package Case 344-15: stainless steel cap with silicone gel isolation, 4-pin lead frame, and P1 side identified by the stainless steel cap per Table 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for output and supply return; must be low-impedance connection to minimize common-mode noise in ratiometric measurements. |
| 2 | +VOUT | Positive output terminal; delivers voltage proportional to applied absolute pressure (0–40 mV at 10 V supply). |
| 3 | VS | Positive supply input; excitation voltage source - output scales ratiometrically, so supply regulation directly impacts measurement accuracy. |
| 4 | –VOUT | Negative output terminal; completes differential output pair - required for noise-rejecting instrumentation amplifier interfaces. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Stabilizes full-scale span and offset over 0°C to +85°C - eliminates need for external thermistor-based correction in portable barometers and altimeters. |
| Ratiometric output | Output voltage scales linearly with supply voltage - allows direct interface to microcontroller ADCs without separate voltage reference, reducing BOM count. |
| Laser-trimmed calibration | Factory-set span and offset via thin-film resistors - achieves ±1.0%VFSS linearity and ±0.5%VFSS offset stability without user calibration. |
| Stainless steel unibody package | Hermetic P1-side sealing with silicone gel protection - enables reliable operation in humid or mildly corrosive environments (e.g., medical airflow paths). |
| Differential output configuration | True 4-pin differential output (+VOUT/–VOUT) - improves common-mode noise rejection in electrically noisy motor-controller or pump-control applications. |
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 |
|---|---|---|---|
| MPXM2202A | Same 0–200 kPa absolute range and ratiometric output, but in MPAK package (Case 1320-02); higher thermal mass, slower warm-up (20 ms vs. MPX2202A's unspecified warm-up). | Preferred for surface-mount automated assembly; less robust mechanical mounting than unibody Case 344-15. | Select MPXM2202A when PCB space is constrained and reflow compatibility is required; MPX2202A remains optimal for ruggedized or through-hole prototyping. |
| MPXV2202GP | Gauge configuration (not absolute); lacks internal vacuum reference; measures pressure relative to ambient - incompatible for barometric/altimeter use without external vacuum reference. | Suitable only where ambient-referenced pressure is needed (e.g., tank level, differential airflow), not absolute pressure. | Do not substitute MPXV2202GP for MPX2202A in absolute pressure applications; verify pressure type (absolute vs. gauge) before selection. |
Compared with MPXM2202A, MPX2202A offers superior mechanical robustness and faster thermal stabilization in unibody packaging, while MPXV2202GP is functionally incompatible due to its gauge reference architecture - making MPX2202A the sole drop-in solution for vacuum-referenced absolute pressure measurement in legacy designs.

FAQ
What is the pressure reference type of the MPX2202A?
The MPX2202A is an absolute pressure sensor with an internal vacuum reference cavity. As stated in the Freescale datasheet Rev 8, the device outputs a voltage that decreases when vacuum is drawn on the P1 port relative to ambient - confirming its absolute reference architecture. This distinguishes MPX2202A from differential or gauge variants like MPX2202DP or MPX2202GP, which require external reference ports.
Does the MPX2202A require external calibration for typical applications?
No, the MPX2202A does not require external calibration for most applications because it features factory laser trimming for span and offset, plus on-chip temperature compensation over 0°C to +85°C. Datasheet Table 1 confirms ±1.0%VFSS linearity and ±0.5%VFSS offset stability - performance levels achieved without user intervention. However, high-accuracy systems may apply one-point system-level calibration to correct residual offset.
What is the correct pin 1 identifier and orientation for MPX2202A (Case 344-15)?
Per Freescale Package Dimensions document CASE 344-15 Issue AA, pin 1 is marked by a chamfered corner on the lead frame and is located adjacent to the stainless steel cap - which identifies the P1 (pressure) side. The pinout is: Pin 1 = GND, Pin 2 = +VOUT, Pin 3 = VS, Pin 4 = –VOUT (Style 1). Orientation is confirmed by the "stainless steel cap" identifier in Table 3 of the MPX2202 datasheet.
Can the MPX2202A operate with supply voltages other than 10 Vdc?
Yes, the MPX2202A operates with supply voltages from unspecified minimum up to 16 Vdc, but its ratiometric output is specified at 10 Vdc typical. Datasheet Table 1 notes that operation above 10 Vdc may induce additional error due to self-heating. For best accuracy and thermal stability, 10 Vdc is recommended; lower voltages reduce output swing proportionally (e.g., 5 V supply yields ~20 mV full scale).
Is the MPX2202A compatible with wet or corrosive media?
No, the MPX2202A is qualified only for dry air as the pressure medium, as explicitly stated on page 5 of the datasheet. Exposure to liquids, oils, or chemically aggressive gases may degrade long-term reliability or cause irreversible damage to the silicone gel-isolated die. For non-air media, consult NXP (ex-Freescale) for qualified alternatives or custom qualification testing - MPX2202A itself is not rated for such use.
