Product details
Overview
MPX2202D from Freescale Semiconductor is a differential pressure sensor with silicon piezoresistive sensing element, on-chip temperature compensation, and ratiometric 40 mV full-scale output at 10 V supply. It delivers ±0.6%VFSS linearity over 0–200 kPa range and operates from −40°C to +125°C. Used in medical diagnostics, pump/motor controllers, and robotics for precise air/gas pressure monitoring.
For engineers reviewing the MPX2202D datasheet, MPX2202D pinout, MPX2202D application, or MPX2202D equivalent, this page provides verified technical context, package mapping to Case 344C-01, confirmed pin functions, real-world use scenarios, and two validated alternative part numbers with documented functional and packaging differences.
Technical Context
The MPX2202D implements a monolithic silicon diaphragm with integrated strain gauge and thin-film resistor network, laser-trimmed for span/offset calibration and temperature compensation across 0°C to +85°C. Its ratiometric output ensures proportional response to supply voltage variations, supporting stable operation with 10 V ±6 V excitation.
Designed for dry air media only, the device features 1.0 ms response time (10%–90%), 6.0 mA supply current, and dual-port differential configuration where P1 is the pressure side (marked side) and P2 is the vacuum reference side. Input/output impedances are 1–2.5 kΩ and 1.4–3.0 kΩ respectively.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–200 kPa differential; defines usable input range without saturation or damage |
| Full Scale Span | 40 mV typical at 10 V supply; enables direct ADC interfacing with minimal gain stages |
| Linearity Error | ±0.6%VFSS (end-point method); specifies worst-case deviation from ideal linear transfer function |
| Operating Temp | −40°C to +125°C; supports industrial and automotive under-hood environments |
| Response Time | 1.0 ms (10%–90%); suitable for dynamic pressure monitoring in closed-loop control |
| Supply Voltage | 10 V typical, up to 16 V max; ratiometric behavior maintains accuracy across supply drift |
| Offset Voltage | ±1.0 mV at min pressure; low offset simplifies zero-pressure calibration in system firmware |
Pinout & Package
MPX2202D uses the Unibody Package Case 344C-01 - a 4-pin, surface-mountable ceramic package with stainless steel cap and silicone gel isolation. Pin 1 is ground, Pin 2 is +VOUT, Pin 3 is +VS, Pin 4 is −VOUT per Style 1 pinout definition in Freescale documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Ground | Reference node for both supply and output; must connect to low-impedance system ground plane |
| Pin 2 | + Output | Positive differential output terminal; voltage rises with increasing P1–P2 pressure difference |
| Pin 3 | + Supply | Excitation input; supplies power to internal bridge and compensation circuitry |
| Pin 4 | − Output | Negative differential output terminal; completes Wheatstone bridge output pair for noise rejection |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Stabilizes full-scale span and offset over 0°C to +85°C, eliminating need for external thermistor networks |
| Ratiometric output | Output scales linearly with supply voltage, enabling direct use with microcontroller ADCs powered from same rail |
| Laser-trimmed calibration | Factory-set span and offset reduce system-level calibration effort and improve batch-to-batch consistency |
| Dual-port differential configuration | Enables bidirectional pressure measurement (positive/negative ΔP) without external vacuum reference |
| Silicone gel isolation | Protects die and wire bonds from environmental contaminants while transmitting pressure signal reliably |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV2202DP | Small Outline Package (Case 1351-01), same 0–200 kPa range and 40 mV FS, but lower 3.5 mA supply current and 2.5 ms response time | Surface-mount footprint differs; requires PCB redesign; better suited for space-constrained consumer electronics vs. industrial modules | Select MPXV2202DP when board area is critical and slower dynamics are acceptable; verify port alignment matches mechanical housing |
| MPXM2202D | MPAK package (Case 1320-02), identical electrical specs, but rated for higher burst pressure (400 kPa) and includes integrated ESD protection | Same pinout but different thermal mass and mounting geometry; preferred in high-vibration or ESD-prone environments like automotive test rigs | Choose MPXM2202D for enhanced reliability in harsh conditions; confirm gasket compatibility with existing port seals |
Compared with MPX2202D, MPXV2202DP trades response speed and package robustness for compactness, while MPXM2202D retains identical performance with improved mechanical ruggedness and ESD tolerance-making it suitable for production-grade industrial deployments where long-term stability outweighs size constraints.

FAQ
What is the pressure media compatibility of the MPX2202D?
The MPX2202D is qualified for use with dry air only. Freescale explicitly states that other media-including moisture, oils, solvents, or corrosive gases-may degrade long-term reliability or cause irreversible performance shift. If your application requires non-air media, consult NXP's factory for compatibility testing reports before design-in. The MPX2202D's silicone gel isolation is optimized for dry gas transmission, not chemical resistance.
Does the MPX2202D require external amplification to interface with a 3.3 V microcontroller ADC?
Yes, the MPX2202D's 40 mV full-scale output at 10 V supply yields only ~13.2 mV at 3.3 V supply due to ratiometric scaling. To achieve sufficient resolution with a 12-bit ADC, a minimum gain of ~25× is required to map 40 mV to ~1 V. The MPX2202D itself contains no internal amplifier; signal conditioning must be implemented externally using instrumentation amplifiers such as the AD8421 or INA128, with attention to input bias current matching.
How is the pressure port orientation identified on the MPX2202D package?
Per Freescale's Pressure (P1)/Vacuum (P2) Side Identification Table, the MPX2202D (Case 344C-01) has the Pressure (P1) side identified by the side with part marking-i.e., the surface bearing the "MPX2202D" laser etch. The opposite side is the Vacuum (P2) port. Correct orientation is critical: applying pressure to P2 instead of P1 will invert the output polarity and may exceed maximum ratings if over-pressurized.
What is the warm-up time specification for the MPX2202D, and why does it matter?
The MPX2202D specifies a 20 ms warm-up time-the duration required after power-on for internal temperature gradients to stabilize and output to settle within final accuracy. This matters in battery-powered or duty-cycled systems where rapid wake-up measurements are needed; readings taken before 20 ms may exhibit up to ±2%VFSS offset error due to thermal transient effects in the compensation circuitry.
Can the MPX2202D be used for absolute pressure measurement?
No, the MPX2202D is strictly a differential pressure sensor. Its internal structure lacks a sealed vacuum reference cavity. For absolute pressure measurement, Freescale specifies the MPX2202A (absolute variant, Case 344-15) which integrates an on-chip vacuum reference. Using MPX2202D in absolute mode-e.g., sealing one port-violates its calibrated design, introduces uncontrolled offset drift, and voids accuracy guarantees stated in the datasheet.
