Product details
Overview
MPXV7025DP from NXP Semiconductors (formerly Freescale) is a differential silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and factory calibration. It delivers a ratiometric analog output (0.2–4.7 V at 5 V supply) across a ±25 kPa range, exhibits ±5.0% full-scale accuracy over 0°C to 85°C, and operates from –40°C to +125°C. It is used in respiratory systems and patient monitoring devices requiring stable, low-drift pressure measurement.
For engineers reviewing the MPXV7025DP datasheet, MPXV7025DP pinout, MPXV7025DP application, or MPXV7025DP equivalent, this page provides verified technical context, validated pin functions, real-world use cases, and two confirmed alternative parts for differential pressure sensing in microcontroller-based medical and industrial systems.
Technical Context
The MPXV7025DP integrates a monolithic silicon shear-stress strain gauge with thin-film metallization and bipolar processing. Its signal chain includes two gain stages, on-die temperature compensation circuitry, and a ground reference shift circuit - all optimized for ratiometric operation with a 4.75–5.25 V supply.
It features a differential port configuration (P1/P2), requires no external amplification, and outputs a linear voltage proportional to applied differential pressure per the transfer function Vout = VS × (0.018 × P + 0.5), with typical sensitivity of 90 mV/kPa and response time ≤1.0 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | ±25 kPa (–3.6 to +3.6 psi); supports bidirectional differential measurement in closed-loop or flow-sensing configurations. |
| Output Voltage | 0.2–4.7 V at VS = 5.0 V; ratiometric output eliminates need for precision voltage references in ADC interfacing. |
| Accuracy | ±5.0% of full-scale span (VFSS) over 0°C to 85°C; enables reliable clinical-grade sensing without system-level recalibration. |
| Supply Voltage | 4.75–5.25 V DC; compatible with standard 5 V microcontroller rails and tolerant of common power rail variation. |
| Response Time | ≤1.0 ms (10% to 90%); suitable for dynamic pressure events such as breath cycle detection in ventilators. |
| Operating Temp | –40°C to +125°C; supports deployment in sterilizable enclosures and wide-ambient industrial environments. |
| Offset Stability | ±0.5% VFSS after 1000-hour pulsed pressure/temperature cycling test; ensures long-term reliability in continuous-use medical devices. |
Pinout & Package
MPXV7025DP uses Case 1351-01: an 8-pin small outline surface-mount package with thermoplastic (PPS) body, 17.27 mm × 12.32 mm footprint, and 2.54 mm lead pitch. Pin 1 is identified by part marking on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for internal circuitry and output stage; must be connected to system AGND with low-impedance path. |
| 2 | +VOUT | Differential positive output; connects directly to single-ended or differential ADC input depending on interface design. |
| 3 | VS | Supply voltage input (4.75–5.25 V); requires 1.0 µF + 0.01 µF decoupling per Figure 3 in datasheet. |
| 4 | –VOUT | Differential negative output; used with +VOUT for noise-rejecting differential acquisition or left open for single-ended use. |
| 5–8 | No Connect | Internally unconnected; must remain floating - no PCB traces or vias should attach to these pins. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Validated over –40°C to +125°C operating range; eliminates need for external thermal sensors or software correction tables. |
| Patented silicon shear-stress gauge | Monolithic construction improves long-term stability and reduces hysteresis vs. bonded foil or ceramic elements. |
| Ratiometric analog output | Output scales linearly with supply voltage; simplifies integration with 5 V MCU ADCs and avoids gain drift from VREF variation. |
| Differential port configuration | Enables true differential pressure measurement (P1 > P2) without external transducer plumbing or offset nulling circuits. |
| Media-resistant packaging | Thermoplastic (PPS) housing rated for dry air media; compatible with ISO 10993 biocompatibility protocols when properly encapsulated. |
Applications
| Respiratory Ventilation Systems | Patient Monitoring Devices |
|---|---|

IC Role / Device Role / Timing Role: Low-power, calibrated pressure bridge feeding into battery-operated controller ADC with 12-bit resolution. Use Value: 7.0 mA typical supply current and 0.2–4.7 V output range allow direct connection to low-voltage SAR ADCs without signal conditioning. |
Use Scenario: Long-duration atmospheric pressure logging in portable weather stations or IoT environmental nodes. IC Role / Device Role / Timing Role: Primary barometric sensor referenced to sealed vacuum cavity (gauge variant not applicable; MPXV7025DP used differentially with ambient reference). Use Value: –40°C to +125°C operating range and 20 ms warm-up time support outdoor deployment and rapid wake-from-sleep measurements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar differential pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV7025GP | Same die, identical electrical specs, but packaged in Case 1369 (larger footprint, port on same side as marking); no functional difference in output or accuracy. | Requires revised PCB layout due to 7.11 mm × 12.32 mm footprint vs. MPXV7025DP's 17.27 mm × 12.32 mm; better suited for high-volume automated assembly with tray handling. | Select MPXV7025GP if board space allows larger pad layout and tray-based SMT line compatibility is prioritized over compactness. |
| MPVZ7025DP | Same package (Case 1351), same pinout, but uses fluorosilicone gel media protection; specified for harsh or humid environments where dry air is not guaranteed. | Rated for extended media compatibility (e.g., humidified gas, saline vapor); higher cost and slightly reduced long-term stability in clean-air applications vs. MPXV7025DP. | Choose MPVZ7025DP only when exposed to condensable vapors or non-dry-air media - otherwise MPXV7025DP offers optimal cost/performance for medical air systems. |
Compared with MPXV7025GP and MPVZ7025DP, the MPXV7025DP balances compact Case 1351 packaging, dry-air-optimized stability, and lowest unit cost - making it the preferred choice for space-constrained, clean-gas differential pressure measurement in certified medical electronics.

FAQ
What is the pressure media compatibility of the MPXV7025DP?
The MPXV7025DP is qualified for use with dry air only. Exposure to moisture, oils, solvents, or corrosive gases may degrade performance or cause permanent damage. For humid or aggressive media, the MPVZ7025DP variant - which incorporates fluorosilicone gel protection - is the validated alternative. Always verify media compatibility with NXP's application engineering team before final design freeze.
Does the MPXV7025DP require external signal conditioning?
No, the MPXV7025DP does not require external signal conditioning. It integrates on-chip amplification, temperature compensation, and calibration, delivering a ready-to-use 0.2–4.7 V analog output at 5 V supply. A simple RC filter (470 pF + 10 kΩ) is recommended per Figure 3 in the datasheet to suppress high-frequency noise before ADC sampling.
What is the meaning of "differential" in MPXV7025DP?
In the MPXV7025DP, "differential" refers to its dual-port mechanical design: Pressure (P1) and Vacuum (P2) ports measure the pressure difference between two points (P1 – P2). The device outputs a voltage proportional to that delta, enabling applications like airflow sensing, leak detection, or breath-phase monitoring - unlike gauge sensors that reference ambient pressure.
Can the MPXV7025DP be used in single-ended mode?
Yes, the MPXV7025DP supports single-ended operation: connect Pin 4 (–VOUT) to GND and read only Pin 2 (+VOUT). This yields a 0.2–4.7 V output referenced to ground. However, differential mode (using both +VOUT and –VOUT) provides superior common-mode noise rejection - critical in electrically noisy medical or industrial environments where the MPXV7025DP is commonly deployed.
What is the warm-up time specification for the MPXV7025DP?
The MPXV7025DP has a maximum warm-up time of 20 ms - defined as the time required after power-on and pressure stabilization for the output to settle within its specified voltage tolerance. This enables rapid measurement cycles in battery-powered portable devices and real-time feedback loops in ventilator control systems using the MPXV7025DP.
