Product details
Overview
MPXV7002GP from NXP Semiconductors is a gauge-pressure silicon piezoresistive transducer with on-chip signal conditioning, factory-calibrated output, and temperature compensation over +10 °C to +60 °C. It delivers a ratiometric analog voltage output (0.25–4.75 V) proportional to pressure in the ±2.0 kPa range, operates from 4.75–5.25 V supply, and draws ≤10 mA - ideal for microcontroller-based respiratory monitoring and HVAC differential sensing.
For engineers reviewing the MPXV7002GP datasheet, MPXV7002GP pinout, MPXV7002GP application, or MPXV7002GP equivalent, this page provides verified pin configuration, pressure-side identification (port-attached side), accuracy budget breakdown (±2.5% VFSS typical), response time (1.0 ms), and real-world use context for medical and industrial analog-sensing designs.
Technical Context
The MPXV7002GP integrates a patented silicon shear-stress strain gauge with thin-film metallization and bipolar signal conditioning circuitry on a monolithic die. Its architecture includes two gain stages, ground-reference shift circuitry, and on-chip temperature compensation - all optimized for stable operation across its specified 10–60 °C ambient range.
It uses a ratiometric transfer function Vout = VS × (0.2 × P(kPa) + 0.5) ±6.25% VFSS, where full-scale span (VFSS) is defined as the algebraic difference between output at +2.0 kPa and −2.0 kPa. The device requires external decoupling (1.0 µF, 0.01 µF, 470 pF) per Figure 6 to meet published operating characteristics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | ±2.0 kPa - supports low-differential applications such as airway pressure monitoring and damper feedback. |
| Output Voltage Range | 0.25–4.75 Vdc at VS = 5.0 V - provides 4.5 V full-scale span for high-resolution ADC interfacing. |
| Accuracy | ±2.5% VFSS typical - includes linearity, TcOffset, TcSpan, and hysteresis contributions over 10–60 °C. |
| Response Time | 1.0 ms (10% to 90%) - enables real-time dynamic pressure tracking in breathing cycle analysis. |
| Supply Voltage | 4.75–5.25 Vdc - ratiometric operation ensures output stability against minor rail variation. |
| Operating Temperature | +10 °C to +60 °C - validated for hospital bed and HVAC enclosure environments. |
| Max Pressure Rating | 75 kPa - mechanical overpressure limit protects sensor diaphragm during installation or fault conditions. |
Pinout & Package
MPXV7002GP uses an 8-pin SO8 thermoplastic (PPS) surface-mount package (SOT1693-3), measuring 12.06 mm × 12.06 mm × 8.38 mm, with 2.54 mm pitch. The pressure port is located on the side with part marking; the gel-coated die face faces the port-attached side (P1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect | Internally unconnected; must be left floating - no external tie required. |
| 2 | Supply Voltage (VS) | Primary power input; requires decoupling per Figure 6 to maintain accuracy and noise immunity. |
| 3 | Ground (GND) | Analog reference return; must be routed with low-impedance path to minimize offset drift. |
| 4 | Voltage Output (Vout) | Ratiometric analog output; directly interfaces to 10–12-bit ADC inputs without amplification. |
| 5–8 | No Connect | All internally unconnected; no external connection or grounding permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Gauge pressure configuration | Single-port design referenced to ambient - eliminates need for vacuum reference plumbing in HVAC or bed position sensing. |
| On-chip temperature compensation | Validated over +10 °C to +60 °C - removes requirement for external thermal calibration in embedded medical devices. |
| Patented silicon shear-stress strain gauge | Monolithic integration improves long-term stability and reduces sensitivity to mounting stress vs. conventional piezoresistive elements. |
| Ratiometric output | Output scales linearly with supply voltage - simplifies system-level calibration when using shared 5 V rails with microcontrollers. |
| Fluorosilicone gel isolation | Protects die and wire bonds from moisture and particulates while transmitting pressure - enables reliable operation in humid respiratory environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV7002DP | Dual-port differential configuration; identical SO8 package (SOT1693-1), same ±2.0 kPa range and accuracy. | Requires two pressure ports and balanced tubing - unsuitable for single-ended gauge use cases like bed sensors. | Select MPXV7002DP only when measuring pressure difference (e.g., filter delta-P); MPXV7002GP is correct for ambient-referenced measurements. |
| MPXV5004GC | Wider range (0–4 kPa), same SO8 footprint (SOT1854-1), but lower accuracy (±5% VFSS) and no auto-zero support. | Not rated for medical respiratory use due to higher error budget and lack of factory zero calibration traceability. | MPXV5004GC may serve cost-sensitive industrial duct monitoring but lacks the clinical-grade stability of MPXV7002GP. |
Compared with MPXV7002DP and MPXV5004GC, the MPXV7002GP offers guaranteed gauge-referenced operation, tighter ±2.5% VFSS accuracy, and fluorosilicone gel protection - making it the only option qualified for regulated medical pressure sensing where ambient reference integrity and long-term zero stability are mandatory.

FAQ
What is the pressure port orientation for MPXV7002GP?
The pressure port for MPXV7002GP is located on the side with the part marking (Case 1369-01). This is the P1 (Pressure) side, identified by the fluorosilicone gel-coated die face visible through the port opening. The opposite side is sealed and non-pressurizable. Correct orientation is critical for valid gauge-referenced measurement.
Does MPXV7002GP require external zero calibration?
No - MPXV7002GP is factory-calibrated and includes on-chip temperature compensation. Its offset is trimmed at production, and the specified ±2.5% VFSS accuracy assumes no user calibration. Auto-zero functionality is not implemented; however, the device maintains stable zero over its +10 °C to +60 °C operating range without drift correction.
Can MPXV7002GP be used with a 3.3 V microcontroller supply?
No - MPXV7002GP requires a 4.75–5.25 V supply (VS) per its Absolute Maximum Ratings and Operating Characteristics. Using 3.3 V will result in invalid output voltage levels and failure to meet datasheet specifications. A dedicated 5 V LDO or DC-DC converter is required for proper operation of MPXV7002GP.
What is the meaning of "n.c." on pins 1 and 5–8 of MPXV7002GP?
"n.c." stands for "no connect" - these pins (1, 5, 6, 7, 8) have no internal connection to the die or signal chain. They must remain unconnected and ungrounded in the PCB layout. Routing traces or applying solder to these pins may introduce parasitic coupling or mechanical stress that degrades MPXV7002GP accuracy or long-term reliability.
Is MPXV7002GP compatible with media other than dry air?
The MPXV7002GP is characterized and qualified for use with dry air as the pressure medium. Exposure to liquids, oils, or corrosive gases may degrade the fluorosilicone gel or damage the silicon diaphragm. For non-air media compatibility, consult NXP's factory directly - no alternate media ratings are published for MPXV7002GP in Rev. 5 documentation.
