Product details
Overview
MPXV7025DPT1 from Freescale Semiconductor is a monolithic silicon differential pressure sensor with on-chip signal conditioning, temperature compensation, and factory calibration. It delivers a ratiometric 0.2–4.7 V analog output over a ±25 kPa range at 5.0 V supply, with ±5.0% full-scale accuracy across 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-power pressure sensing.
For engineers reviewing the MPXV7025DPT1 datasheet, MPXV7025DPT1 pinout, MPXV7025DPT1 application, or MPXV7025DPT1 equivalent, this page provides verified technical context, package mapping, real-world use cases, and validated alternative options for medical and industrial pressure-sensing designs.
Technical Context
The MPXV7025DPT1 integrates a patented silicon shear-stress strain gauge with thin-film metallization and bipolar processing to generate a high-level analog output directly proportional to applied differential pressure. Its on-chip circuitry includes two gain stages, temperature compensation, and ground reference shift circuitry - all optimized for microcontroller A/D interfacing.
It requires external decoupling (1.0 µF + 0.01 µF + 470 pF) per Figure 3 to meet electrical specifications. The transfer function is Vout = VS × (0.018 × P + 0.5), with temperature-dependent error multipliers (1× at 0–85°C, 3× at –40°C/+125°C) and a 1.0 ms typical response time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | ±25 kPa (–3.6 to +3.6 psi); supports bidirectional differential measurement with P1 > P2 orientation. |
| Output Voltage | 0.2–4.7 V at VS = 5.0 V; ratiometric scaling ensures consistent A/D resolution across supply variation. |
| Accuracy | ±5.0% of full-scale span (VFSS) over 0°C to 85°C; enables reliable clinical-grade pressure detection without external calibration. |
| Supply Current | Typ. 7.0 mA at 5.0 V; compatible with low-power embedded systems and battery-operated monitoring devices. |
| Response Time | Typ. 1.0 ms (10% to 90%); suitable for dynamic respiratory waveform capture and real-time feedback control. |

| Sensitivity | Typ. 90 mV/kPa; provides high-resolution analog output for precise pressure delta detection in low-range applications. |
Pinout & Package
MPXV7025DPT1 uses the Small Outline Package (Case 1351-01), thermoplastic (PPS) surface-mount housing with 8-pin configuration and dual port access. Pin 1 is identified by part marking on the Pressure (P1) side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for internal circuitry and output stage; must be connected to system common ground. |
| 2 | +Vout | Positive analog output terminal; delivers conditioned voltage proportional to differential pressure (P1 − P2). |
| 3 | VS | Supply input (4.75–5.25 V); powers internal amplifier, compensation, and sensing elements. |
| 4 | −Vout | Differential output complement; used with instrumentation amplifiers for noise-rejecting measurements. |
| 5–8 | No Connect | Internally unconnected; no PCB routing or termination required. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Validated over –40°C to +125°C; eliminates need for external thermal sensors or software correction in wide-temperature deployments. |
| Patented silicon shear-stress gauge | Monolithic micromachined element with high linearity and long-term stability; reduces drift under cyclic pressure loading. |
| Ratiometric output | Output scales linearly with supply voltage; preserves A/D resolution when using shared MCU reference or unregulated supplies. |
| Dual-port differential configuration | Enables true differential pressure measurement (e.g., airway vs. ambient) without external transducer plumbing or offset nulling. |
| Factory-calibrated transfer function | Delivers known Vout = VS × (0.018 × P + 0.5) ± error; removes calibration step during system integration and reduces BOM count. |
Applications
| Respiratory Ventilation Systems | Patient Monitoring Devices |
|---|---|
Use Scenario: Real-time airway pressure monitoring during mechanical ventilation to trigger breath cycles and detect obstructions. IC Role / Device Role / Timing Role: Differential pressure transducer measuring ΔP between inspiratory and expiratory limbs of breathing circuit.

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV7002DP | Narrower ±2 kPa range; same 8-pin SOIC package and ratiometric output; lower sensitivity (180 mV/kPa). | Better suited for ultra-low-pressure applications like leak detection or microfluidic flow control. | Select MPXV7002DP only if pressure range is ≤±2 kPa and higher sensitivity is required; not a direct replacement for ±25 kPa use cases. |
| MPXV5004DP | Wider ±100 kPa range; same pinout and supply; higher full-scale output (0.2–4.7 V remains, but scaled to larger range). | Appropriate for high-dynamic-range applications such as compressor discharge monitoring or pneumatic actuator feedback. | Choose MPXV5004DP when measuring >±25 kPa differentials; accuracy degrades to ±5.0% of its own 100 kPa span, reducing resolution at low pressures. |
Compared with MPXV7025DPT1, MPXV7002DP offers finer resolution in sub-kPa ranges but cannot cover ±25 kPa, while MPXV5004DP extends upper range at the cost of reduced low-end sensitivity - making MPXV7025DPT1 optimal for mid-range medical and industrial differential pressure tasks.

FAQ
What is the pressure range and output behavior of the MPXV7025DPT1?
The MPXV7025DPT1 has a differential pressure range of ±25 kPa (–3.6 to +3.6 psi) and delivers a ratiometric analog output from 0.2 V to 4.7 V at 5.0 V supply. Its transfer function is Vout = VS × (0.018 × P + 0.5), where P is pressure in kPa. Output saturates outside the specified range, and the device is calibrated for ±5.0% full-scale accuracy over 0°C to 85°C. This behavior makes MPXV7025DPT1 ideal for precision respiratory and process monitoring.
How is the MPXV7025DPT1 packaged and mounted?
The MPXV7025DPT1 uses Case 1351-01 - an 8-pin small-outline surface-mount package made of thermoplastic PPS. Pin 1 is identified by part marking on the Pressure (P1) side. The footprint must follow Freescale's recommended layout (Figure 4), including solder mask to prevent bridging. It is supplied in trays and requires standard reflow soldering; no special handling beyond standard SMT protocols is needed for MPXV7025DPT1.
Does the MPXV7025DPT1 require external signal conditioning?
No, the MPXV7025DPT1 includes full on-chip signal conditioning: temperature compensation, gain staging, and offset correction. It outputs a ready-to-use analog voltage (0.2–4.7 V) that interfaces directly with microcontroller A/D inputs. However, Freescale recommends a decoupling network (1.0 µF + 0.01 µF + 470 pF) on the supply line to meet electrical specs - this is not signal conditioning but power integrity support for MPXV7025DPT1.
What media compatibility considerations apply to the MPXV7025DPT1?
The MPXV7025DPT1 is qualified for use with dry air as the pressure medium. Other media - especially corrosive, condensing, or particulate-laden gases - may degrade performance or reliability. Freescale specifies fluorosilicone gel protection on the P1 side, but long-term exposure to non-dry-air media requires factory consultation. For MPXV7025DPT1 deployed in medical gas or HVAC applications, validation against actual media is essential prior to qualification.
Can the MPXV7025DPT1 be used in absolute or gauge configurations?
No - the MPXV7025DPT1 is exclusively a differential pressure sensor (dual-port). Its ordering code "DP" explicitly denotes differential configuration. While the MPXV7025 series includes gauge variants (e.g., MPXV7025GP), the MPXV7025DPT1 has dedicated P1 and P2 ports and internal circuitry optimized for ΔP measurement. It cannot be repurposed as an absolute or sealed-gauge sensor without hardware modification, which is not supported for MPXV7025DPT1.
