Product details
Overview
MPX2100ASX from Freescale Semiconductor is an absolute-pressure silicon piezoresistive sensor with on-chip temperature compensation and laser-trimmed calibration, delivering 40 mV full-scale output at 10 V supply across 0–100 kPa range, used in barometric sensing and vacuum-referenced pressure monitoring.
For engineers reviewing the MPX2100ASX datasheet, MPX2100ASX pinout, MPX2100ASX application, or MPX2100ASX equivalent, this page provides verified technical context, package mapping to Case 344F-01, ratiometric output behavior, linearity (±1.0% VFSS), and validated alternatives for absolute-pressure measurement systems requiring stable offset and span over –40°C to +125°C.
Technical Context
The MPX2100ASX integrates a monolithic silicon diaphragm with embedded strain gauges and thin-film resistor networks for direct voltage output proportional to applied absolute pressure. Its internal circuitry includes laser-trimmed calibration for span and offset, plus passive temperature compensation over 0°C to +85°C.
It operates ratiometrically with supply voltage (10 V typical, up to 16 V max), exhibits 1.0 ms response time (10%–90%), and maintains ±0.5% VFSS offset stability after 1000-hour pulsed pressure/temperature cycling. The device uses dry air as specified pressure media; alternate media require factory validation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–100 kPa absolute; enables barometric and sealed-vacuum chamber monitoring without external reference. |
| Full Scale Span | 38.5–41.5 mV at 10 V supply; provides high-resolution analog output scalable via ADC reference matching. |
| Linearity Error | ±1.0% VFSS (end-point method); defines worst-case deviation from ideal linear transfer function across full scale. |
| Offset Voltage | –2.0 to +2.0 mV at 0 kPa; sets baseline output for zero-pressure calibration in system firmware. |
| Supply Voltage | 10 V typical, 16 V maximum; ratiometric operation ensures output scaling tracks supply variations. |
| Response Time | 1.0 ms (10%–90%); supports dynamic pressure capture in pump control and robotics feedback loops. |
| Operating Temp | –40°C to +125°C; allows deployment in automotive under-hood and industrial ambient environments. |
Pinout & Package
MPX2100ASX uses the unibody Case 344F-01 package - a 4-pin, surface-mountable ceramic carrier with stainless steel cap and port-attached P1 side identification per Freescale documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | GND | Ground reference for both supply and output; must be low-impedance to minimize offset drift. |
| Pin 2 | +VOUT | Positive differential output; delivers voltage proportional to absolute pressure relative to internal vacuum reference. |
| Pin 3 | VS | Supply input; powers sensing element and compensation circuitry; ratiometric scaling applies here. |
| Pin 4 | –VOUT | Negative differential output; completes Wheatstone bridge output path; referenced to GND in single-ended use. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Validated over 0°C to +85°C; eliminates need for external thermistor-based correction in most applications. |
| Laser-trimmed calibration | Ensures <±0.5% VFSS offset stability and <±1.0% VFSS linearity without post-assembly trimming. |
| Ratiometric output | Output scales linearly with VS; simplifies interface to microcontrollers with shared ADC reference. |
| Absolute pressure configuration | Internal vacuum reference enables true atmospheric or sealed-system pressure measurement without external venting. |
| Dry-air media qualification | Specified performance guaranteed only with dry air; chemical compatibility requires factory consultation. |
Applications
| Barometric Pressure Monitoring | Pump/Motor Control Feedback |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute-pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5100AP | Higher supply voltage range (4.75–30 V), integrated signal conditioning, 5 V output; larger Case 402 package. | Requires no external amplifier; suited for 5 V microcontroller systems with space for larger footprint. | Select MPX5100AP when board space permits and 5 V rail simplifies signal chain integration. |
| SPX301-100 | 0–100 kPa absolute range, 0.5% FS accuracy, I²C digital output; SOIC-8 package with internal ADC and EEPROM calibration. | Eliminates analog front-end design; supports multi-sensor daisy-chaining and remote calibration updates. | Select SPX301-100 when digital interface, higher accuracy, or field-updatable calibration is required. |
Compared with MPX2100ASX, MPX5100AP offers wider supply flexibility and built-in amplification but requires more PCB area, while SPX301-100 replaces analog signal conditioning with digital intelligence at the cost of added firmware complexity and higher unit price.

FAQ
What is the pressure type supported by MPX2100ASX?
The MPX2100ASX is an absolute-pressure sensor with an internal vacuum reference. It measures pressure relative to perfect vacuum, not ambient atmosphere or a second port. This makes MPX2100ASX suitable for barometric sensing, altimeters, and sealed-system monitoring where a fixed reference is required. Its P1 side (port-attached) must be exposed to the measured pressure, while the internal vacuum cavity serves as the reference.
What is the correct pinout configuration for MPX2100ASX?
The MPX2100ASX uses Style 1 pinout per Freescale documentation for Case 344F-01: Pin 1 = GND, Pin 2 = +VOUT, Pin 3 = VS (supply), Pin 4 = –VOUT. This matches the differential output configuration shown in Figure 1 and is confirmed in the PACKAGE DIMENSIONS section. Incorrect orientation-especially swapping VS and GND-can damage the device or produce invalid output.
Does MPX2100ASX require external temperature compensation?
No, MPX2100ASX does not require external temperature compensation. It features on-chip passive temperature compensation validated over 0°C to +85°C, with specified TCVoff ≤ ±1.0 mV and TCVFSS ≤ ±1.0% VFSS. While full-range operation extends to –40°C to +125°C, compensation performance is guaranteed only within the 0°C to +85°C band per datasheet Table 1.
Can MPX2100ASX be used with media other than dry air?
MPX2100ASX operating characteristics and reliability data are qualified only for dry air. Use with other gases or liquids may degrade long-term performance or cause failure due to chemical interaction with the silicone gel encapsulant or silicon diaphragm. Freescale explicitly advises contacting the factory for media compatibility validation before deploying MPX2100ASX with non-dry-air media.
What is the maximum overpressure rating for MPX2100ASX?
The MPX2100ASX has a maximum pressure rating of 400 kPa (Table 2, Maximum Ratings), which is four times its full-scale range of 0–100 kPa. Exceeding 400 kPa may cause permanent mechanical deformation of the silicon diaphragm or bond wire failure. This overpressure limit applies regardless of duration or temperature and is not recoverable.
