Product details
Overview
MPX2100DP from Freescale Semiconductor is a differential silicon piezoresistive pressure sensor with on-chip temperature compensation and laser-trimmed calibration, delivering 40 mV full-scale output at 10 V supply, ±0.25% linearity over 0–100 kPa range, and operation from –40°C to +125°C - used in precision pump/motor controllers and medical diagnostics requiring stable ratiometric analog output.
For engineers reviewing the MPX2100DP datasheet, MPX2100DP pinout, MPX2100DP application, or MPX2100DP equivalent, this page provides verified technical context, package-validated pin functions, real-world use scenarios, and two confirmed alternative parts for differential pressure sensing in industrial and medical systems.
Technical Context
The MPX2100DP implements a monolithic silicon diaphragm with integrated strain gauge and thin-film resistor network, enabling direct voltage output proportional to differential pressure (P1 > P2). Its on-chip circuitry includes laser-trimmed span/offset calibration and temperature compensation across 0°C to +85°C.
It operates ratiometrically to supply voltage (10 V typical, up to 16 V max), exhibits 1.0 ms response time (10%–90%), and maintains ±0.1%VFSS pressure hysteresis over its 0–100 kPa range - with offset stability of ±0.5%VFSS after 1000-hour pulsed pressure/temperature cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0 to 100 kPa (0 to 14.5 psi) - supports low-pressure differential measurement in HVAC and fluid control systems. |
| Full Scale Span | 40 mV typical at 10 V supply - enables direct ADC interfacing without amplification in 12-bit+ systems. |
| Linearity Error | ±0.25% VFSS (end-point method) - ensures high accuracy across full scale without software linearization. |
| Supply Voltage | 10 Vdc typical, 16 Vdc max - ratiometric operation preserves accuracy with supply variation in embedded power rails. |
| Response Time | 1.0 ms (10% to 90%) - suitable for dynamic pressure monitoring in motor-driven pumps and robotics. |
| Operating Temp | –40°C to +125°C - validated for under-hood automotive and industrial environments with wide thermal swing. |
| Temperature Effect on Offset | ±1.0 mV over 0°C to +85°C - minimized drift enables stable zero-point reference in unregulated enclosures. |
Pinout & Package
MPX2100DP uses the CASE 344C-01 unibody package - a 4-pin, surface-mountable ceramic chip carrier with stainless steel cap and silicone gel isolation. Pressure side (P1) is identified by the side bearing part marking per Freescale's identification table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for both supply and output; must be low-impedance to minimize common-mode error. |
| 2 | +VOUT | Positive differential output terminal; delivers voltage proportional to P1–P2 pressure difference. |
| 3 | VS | Positive supply input (10 V typical); powers sensing element and compensation circuitry. |
| 4 | –VOUT | Negative differential output terminal; completes Wheatstone bridge output path for true differential readout. |
Key Features
| Feature | Design Value |
|---|---|
| Differential pressure configuration | Optimized for bidirectional P1–P2 measurement with no internal vacuum reference - ideal for flow and leak detection. |
| On-chip temperature compensation | Validated over 0°C to +85°C, reducing external calibration effort and improving long-term stability in ambient-varying systems. |
| Laser-trimmed span and offset | Eliminates need for external potentiometers or digital trimming in production, lowering BOM count and assembly cost. |
| Ratiometric output | Output scales linearly with supply voltage, allowing shared reference between sensor and ADC for improved noise immunity. |
| Silicone gel isolation | Protects die and wire bonds from moisture and particulates while transmitting pressure signal - extends reliability in harsh environments. |
Applications
| Pump/Motor Controllers | Medical Diagnostics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV7025DP | Higher sensitivity (25 mV/kPa vs. 0.4 mV/kPa), integrated signal conditioning, I²C output - requires digital interface and external power regulation. | Targets smart sensors needing self-contained calibration and digital output; not drop-in for analog-only designs. | Select MPXV7025DP only if migrating to digital architecture and accepting higher unit cost for reduced external components. |
| SDX100D4 | Same 0–100 kPa range and differential configuration, but with 5 V supply, 2.5 V ratiometric output, and ±0.5% linearity - lower accuracy, simpler biasing. | Better suited for cost-sensitive consumer devices where ±0.5% linearity is acceptable and 5 V rail is standard. | Choose SDX100D4 when supply is fixed at 5 V and system-level calibration can absorb extra 0.25% nonlinearity margin. |
Compared with MPX2100DP, MPXV7025DP adds digital intelligence at the expense of analog simplicity and pin compatibility, while SDX100D4 trades linearity and supply flexibility for lower cost and ease of integration in 5 V systems - making MPX2100DP optimal for high-accuracy, 10 V-based analog signal chains.

FAQ
What is the pressure type supported by the MPX2100DP?
The MPX2100DP is a differential pressure sensor configured for P1 > P2 operation, where pressure is applied to the marked side (P1) and vacuum or reference pressure to the opposite port (P2). It does not contain an internal vacuum reference like absolute variants (e.g., MPX2100A), and its output increases with rising differential pressure - confirmed in Freescale's Pressure (P1)/Vacuum (P2) Side Identification Table and Figure 1 schematic.
What is the correct pinout configuration for MPX2100DP?
The MPX2100DP uses Style 1 pinout per CASE 344C-01 package documentation: Pin 1 = GND, Pin 2 = +VOUT, Pin 3 = VS (supply), Pin 4 = –VOUT. This matches the block diagram in Figure 1 and is explicitly labeled in the "PACKAGE DIMENSIONS" section for CASE 344C-01 - ensuring proper differential output polarity and grounding for signal integrity.
Does MPX2100DP require external temperature compensation?
No, MPX2100DP includes on-chip temperature compensation validated over 0°C to +85°C, as stated in the Features list and Operating Characteristics table. Its TCVoff and TCVFSS specs (±1.0 mV and ±1.0%VFSS) reflect residual drift after internal compensation - eliminating need for external thermistors or software correction in most applications.
What is the maximum pressure rating for MPX2100DP?
The MPX2100DP has a maximum pressure rating of 400 kPa (Table 2, Maximum Ratings), which is four times its full-scale range of 0–100 kPa. This overpressure tolerance allows safe operation during transient spikes in hydraulic or pneumatic systems without permanent damage or calibration shift.
Can MPX2100DP operate from a 5 V supply?
No - MPX2100DP is specified for 10 Vdc typical supply (with 16 Vdc absolute maximum), and its 40 mV full-scale output assumes 10 V excitation. Operating at 5 V would reduce output to ~20 mV and fall outside guaranteed performance (e.g., linearity, offset), as confirmed in Table 1 where VS min is not defined and typ/max are centered at 10 V.
