Product details
Overview
MPXV7025GC6U from Freescale Semiconductor is a gauge-configured, monolithic silicon piezoresistive 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 to +25 kPa range at 5.0 V supply, with ±5.0% full-scale accuracy across 0°C to 85°C, and is housed in a thermoplastic (PPS) small-outline surface-mount package (Case 482A-01). It is designed for direct interface with microcontroller A/D inputs in medical respiratory systems.
For engineers reviewing the MPXV7025GC6U datasheet, MPXV7025GC6U pinout, MPXV7025GC6U application, or MPXV7025GC6U equivalent, key selection considerations include its gauge pressure sensing mode, 1.0 ms response time, ±200 kPa maximum pressure rating, –40°C to +125°C operating temperature range, and compatibility with dry air media only.
Technical Context
The MPXV7025GC6U integrates a patented silicon shear-stress strain gauge with thin-film metallization and bipolar processing on a single die. Its signal chain includes on-chip temperature compensation circuitry, dual gain stages, and ground-reference shift circuitry - all optimized for ratiometric operation with a 4.75–5.25 V supply.
It operates exclusively in gauge configuration (P1 > P2), where the port-attached side is designated as the Pressure (P1) side protected by fluorosilicone gel. The transfer function is defined as Vout = VS × (0.018 × P + 0.5), with error bands scaled by temperature-dependent multipliers (1× at 0–85°C, 3× at –40°C/+125°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | –25 to +25 kPa gauge: supports bidirectional differential pressure measurement relative to ambient, suitable for low-pressure airflow monitoring. |
| Output Voltage | 0.2 to 4.7 V at VS = 5.0 V: ratiometric analog output directly compatible with 5 V microcontroller ADC references. |
| Accuracy | ±5.0% of full-scale span (VFSS) over 0°C to 85°C: total error includes offset, sensitivity, and nonlinearity under specified thermal conditions. |
| Response Time | 1.0 ms (10% to 90%): enables real-time capture of transient pressure events in ventilator breath cycles or process control feedback loops. |
| Operating Temperature | –40°C to +125°C: wide junction temperature range supports deployment in automotive engine bays or sterilized medical enclosures. |
| Supply Current | 7.0 mA typical at 5.0 V: low quiescent power enables battery-operated portable patient monitors without thermal derating. |
| Maximum Pressure | 200 kPa (P1 > P2): robust overpressure tolerance prevents damage during system startup surges or calibration faults. |
Pinout & Package
MPXV7025GC6U uses the Small Outline Package (Case 482A-01), measuring 10.67 mm × 10.67 mm × 3.18 mm (0.42″ × 0.42″ × 0.125″), with gull-wing leads and a port-attached pressure side identified per Freescale's P1/P2 designation table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | GND | Analog ground reference for internal compensation circuitry and output stage; must be connected to system AGND with low-impedance path. |
| Pin 2 | +VOUT | Single-ended analog output terminal; delivers conditioned voltage proportional to applied gauge pressure (P1 – P2). |
| Pin 3 | VS | Positive supply input (4.75–5.25 V); powers all internal circuitry and defines output scale via ratiometric relationship. |
| Pin 4 | –VOUT | Not used in gauge configuration; internally tied to GND - must remain unconnected or grounded per datasheet guidance. |
| Pins 5–8 | No Connect | Unused bond pads; electrically isolated and must not be soldered or routed to avoid parasitic coupling or mechanical stress. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Validated over –40°C to +125°C ambient, reducing system-level calibration burden and enabling stable operation without external thermistors. |
| Patented silicon shear-stress strain gauge | Monolithic micromachined element delivering high repeatability and long-term stability versus bonded foil or ceramic sensors. |
| Ratiometric output architecture | Output scales linearly with supply voltage, eliminating errors from VS drift and simplifying power supply design in mixed-signal systems. |
| Fluorosilicone gel-protected P1 side | Enables reliable operation with dry air media while preventing moisture ingress and die corrosion in humid environments like respiratory circuits. |
| Small-outline surface-mount package | Case 482A-01 footprint supports automated reflow assembly and compact PCB layouts in space-constrained medical devices. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV5050GP | Wider 0–50 kPa range, higher 0.5–4.5 V output span, same Case 1369 package; no P1/P2 gel protection. | Designed for industrial pressure ranges beyond ±25 kPa; lacks fluorosilicone barrier for harsh media. | Select when higher full-scale pressure and lower offset drift are prioritized over medical-grade media isolation. |
| MP3V5050G | Same –25 to +25 kPa range but in smaller 6-pin SOT-23 package; 0.1–4.9 V output; ±3.0% accuracy over 0–85°C. | Targeted at ultra-compact consumer wearables; lacks extended –40°C to +125°C operation and gel protection. | Select when board space is critical and medical-grade reliability is not required. |
Compared with MPXV7025GC6U, MPXV5050GP offers higher pressure headroom but no gel barrier, while MP3V5050G reduces footprint and improves accuracy marginally but sacrifices temperature range and media compatibility - making MPXV7025GC6U optimal for regulated medical gauge-sensing where long-term stability and dry-air compatibility are mandatory.

FAQ
What pressure type does the MPXV7025GC6U measure?
The MPXV7025GC6U measures gauge pressure - meaning it reports pressure relative to ambient atmospheric pressure. Its P1 port is exposed to the measured pressure, while P2 is vented to atmosphere through the package. This configuration makes MPXV7025GC6U ideal for applications like airway pressure monitoring where differential-to-ambient measurement is required.
Can the MPXV7025GC6U be used with media other than dry air?
No - the MPXV7025GC6U is qualified and characterized only for use with dry air as the pressure medium. Freescale explicitly states that other media may degrade performance or reliability due to chemical incompatibility with the fluorosilicone gel on the P1 side. For alternative media, consult NXP's factory for validated alternatives before deploying MPXV7025GC6U in non-dry-air systems.
What is the recommended decoupling network for the MPXV7025GC6U?
The MPXV7025GC6U requires a decoupling network as shown in Figure 3 of its datasheet: a 1.0 µF bulk capacitor, a 0.01 µF ceramic capacitor, and a 470 pF filter capacitor between VS and GND. This network stabilizes the supply rail and suppresses high-frequency noise that could corrupt the analog output - essential for achieving the specified ±5.0% accuracy in MPXV7025GC6U systems.
Is the MPXV7025GC6U pin-compatible with other MPXV7025 variants?
Yes - MPXV7025GC6U shares identical pinout (Style 1: Pin 1 = GND, Pin 2 = +VOUT, Pin 3 = VS, Pin 4 = –VOUT, Pins 5–8 = NC) and Case 482A-01 package with MPXV7025GC6T1 and MPXV7025GP. However, MPXV7025GC6U is supplied in rails, while GC6T1 is tape-and-reel and GP is in trays - all share identical electrical and mechanical specifications for MPXV7025GC6U.
Does the MPXV7025GC6U require external calibration after soldering?
No - the MPXV7025GC6U is fully temperature-compensated and factory-calibrated across –40°C to +125°C. Its offset and sensitivity are trimmed during manufacturing, and the on-chip compensation circuitry maintains accuracy without user calibration. System-level validation is still recommended, but MPXV7025GC6U eliminates the need for post-assembly trimming or lookup-table compensation in most designs.
