Product details
Overview
MPXM2202A from NXP Semiconductors (formerly Freescale) is an absolute pressure sensor IC with on-chip temperature compensation, delivering a ratiometric analog voltage output proportional to applied pressure in the 0–200 kPa range. It features 40 mV full-scale span (typ), ±1.0 mV offset (typ), and ±1.0% VFSS linearity over 0°C to +85°C - used in medical diagnostics, barometric sensing, and industrial pressure switching.
For engineers reviewing the MPXM2202A datasheet, MPXM2202A pinout, MPXM2202A application, or MPXM2202A equivalent, this page provides verified technical context, package mapping to CASE 1320-02, calibrated performance data, and two validated alternative part numbers for pressure-sensing system design.
Technical Context
The MPXM2202A integrates a monolithic silicon piezoresistive diaphragm with laser-trimmed thin-film resistor networks for precise span and offset calibration. Its on-chip temperature compensation circuitry actively corrects for TcSpan (±2.0% VFSS) and TcOffset (±1.0 mV) across –40°C to +125°C operating range.
It operates ratiometrically with 10 Vdc supply (6.0 mA typical current), delivering linear differential voltage output referenced to ground. Input impedance is 1000–2500 Ω; output impedance is 1400–3000 Ω; 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 input range for medical barometers and vacuum-assisted level indicators. |
| Full Scale Span | 38.5–41.5 mV at 10 Vdc - enables direct ADC interface without gain stage in 12-bit systems with ≥1.2 mV LSB resolution. |
| Offset Voltage | –2.0 to +2.0 mV at min pressure - supports zero-pressure reference calibration in closed-loop control systems. |
| Linearity Error | ±1.0% VFSS (end-point method) - ensures ≤2.0 mV absolute nonlinearity error over full scale at 25°C. |
| Temperature Compensation | 0°C to +85°C - guarantees stable offset and span within spec without external thermistor network. |
| Response Time | 1.0 ms (10%–90%) - suitable for dynamic pressure monitoring in pump/motor controllers with <1 kHz update requirements. |
| Supply Voltage | 10 Vdc nominal (6–16 Vdc range) - allows operation from standard industrial 12 V rails with margin for ripple. |
Pinout & Package
MPXM2202A uses the MPAK package (CASE 1320-02), a 4-pin surface-mount ceramic package with ported pressure inlet on the marked side. Pin 1 is ground, Pin 2 is +VOUT, Pin 3 is VS (+supply), Pin 4 is –VOUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Ground (GND) | Reference node for both supply and output; must be low-impedance connection to minimize common-mode error. |
| Pin 2 | + Output (VOUT+) | High-side analog output terminal; delivers voltage proportional to pressure relative to GND. |
| Pin 3 | + Supply (VS) | Excitation input; device output scales ratiometrically with this voltage - critical for supply-referenced ADC designs. |
| Pin 4 | – Output (VOUT–) | Differential output complement; used with instrumentation amplifier for noise rejection in EMI-prone environments. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Eliminates need for external thermistor network or digital correction in 0–85°C applications. |
| Ratiometric output | Output voltage tracks supply variations - simplifies system-level calibration when using same rail for ADC reference. |
| Laser-trimmed calibration | Factory-set span and offset reduce post-assembly trimming effort and improve batch consistency. |
| MPAK ceramic package | Hermetic ported construction enables long-term stability in humid or chemically aggressive environments. |
| Low power consumption | 6.0 mA typical supply current allows integration into battery-powered portable diagnostic devices. |
Applications
| Medical Diagnostics | Barometric Sensing |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV7025DP | 25 kPa range, SOIC-8 package, 0.25% VFSS linearity, 3.3 V supply - higher precision but narrower range. | Best for low-range differential pressure in clean-air ventilation control, not direct replacement for 200 kPa absolute use. | Select when sub-kPa resolution is required and system operates at 3.3 V; verify PCB layout for SOIC-8 footprint. |
| MPX5700AP | 700 kPa range, 8-pin DIP, 1.5% VFSS linearity, 5 V supply - wider range but lower accuracy and larger package. | Suitable for high-pressure industrial hydraulics where 200 kPa is insufficient; requires different mounting and porting. | Choose only if pressure exceeds 200 kPa; note that 5 V supply and DIP package demand board redesign. |
Compared with MPXM2202A, MPXV7025DP offers tighter linearity but cannot measure full atmospheric range, while MPX5700AP extends upper range at cost of accuracy and board space - MPXM2202A remains optimal for 0–200 kPa absolute applications requiring MPAK reliability and 10 V compatibility.

FAQ
What is the pressure type supported by MPXM2202A?
The MPXM2202A is an absolute pressure sensor, meaning it measures pressure relative to a sealed internal vacuum reference. Its specified range is 0–200 kPa absolute, making it suitable for barometric, altimeter, and sealed-system monitoring applications where ambient atmospheric pressure serves as the baseline.
Does MPXM2202A require external temperature compensation?
No, MPXM2202A includes on-chip temperature compensation circuitry calibrated over 0°C to +85°C. This eliminates the need for external thermistors or software correction algorithms in most applications, as TcSpan (±2.0% VFSS) and TcOffset (±1.0 mV) are already factored into its specified performance.
What is the supply voltage requirement for MPXM2202A?
MPXM2202A operates with a nominal supply voltage of 10 Vdc, rated from 6 Vdc to 16 Vdc. Its output is ratiometric - scaling linearly with supply voltage - so using the same rail for both excitation and ADC reference improves system accuracy without additional regulation.
Can MPXM2202A be used in differential pressure configurations?
No, MPXM2202A is configured exclusively for absolute pressure measurement. For differential pressure, Freescale's MPXM2202D or MPX2202DP variants are designated - they feature dual ports and distinct internal architecture optimized for P1–P2 sensing, unlike the single-port vacuum-referenced design of MPXM2202A.
What package type does MPXM2202A use, and how is pressure ported?
MPXM2202A uses the MPAK package (CASE 1320-02), a 4-pin ceramic surface-mount housing. Pressure is applied to the side marked with device identification; this is the P1 (pressure) side, while the opposite side is sealed to vacuum. The port is integrated into the package body and requires direct media contact or tubing interface.
