Product details
Overview
MPXV7002GC6U from NXP Semiconductors is a gauge-configured, monolithic silicon piezoresistive pressure sensor with on-chip signal conditioning, factory calibration, and temperature compensation over +10 °C to +60 °C. It delivers a ratiometric analog output (0.25–4.75 V) proportional to differential pressure (±2.0 kPa) at 5.0 V supply, with ±2.5 %VFSS accuracy and 1.0 ms response time - used in respiratory systems and hospital bed pressure monitoring.
For engineers reviewing the MPXV7002GC6U datasheet, MPXV7002GC6U pinout, MPXV7002GC6U application, or MPXV7002GC6U equivalent, key selection criteria include its SO8 thermoplastic (PPS) surface-mount package (SOT1854-1), gauge pressure configuration, 4.75–5.25 V supply range, 10 mA max supply current, and compatibility with microcontroller ADC interfaces requiring low-drift, self-contained analog output.
Technical Context
The MPXV7002GC6U integrates a patented silicon shear-stress strain gauge with thin-film metallization and bipolar processing on a single die. Its internal architecture includes two gain stages, temperature compensation circuitry, and ground reference shift circuitry - all optimized for stable operation across its specified temperature range.
This device operates exclusively in gauge pressure mode with one port exposed to ambient pressure (P2) and the other to measured pressure (P1), as identified by the port-attached side per Case 482A-01. It requires no external zeroing circuitry but benefits from the decoupling network shown in Figure 6 (1.0 µF, 0.01 µF, 470 pF) to meet full-spec performance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV5004GC | Wider range (±4 kPa), higher full-scale output (0.2–4.8 V), same SO8 package (SOT1854-1) | Better suited for higher-pressure HVAC or industrial process monitoring where ±2 kPa is insufficient | Select MPXV5004GC when system pressure exceeds ±2.0 kPa; otherwise MPXV7002GC6U offers tighter accuracy budget at lower range |
| MPXV7025GC | Same ±2.5 kPa range but ±1.5 %VFSS accuracy, wider temp range (−40 °C to +125 °C), identical pinout/package | Required for automotive or outdoor industrial use where extended temperature operation is mandatory | Choose MPXV7025GC only if operating below +10 °C or above +60 °C is needed; MPXV7002GC6U remains optimal for medical/indoor applications |

FAQ
What is the pressure port configuration of the MPXV7002GC6U?
The MPXV7002GC6U is a gauge pressure sensor with a single pressure port (P1) on the side marked "Port Attached" per Case 482A-01 package outline. The opposite side (P2) is vented to ambient atmosphere. This configuration measures pressure relative to local atmospheric pressure - critical for applications like respiratory flow or bed pressure where absolute reference is unnecessary.
Does the MPXV7002GC6U require external zeroing or calibration during system operation?
No, the MPXV7002GC6U is factory-calibrated and includes on-chip temperature compensation over +10 °C to +60 °C. Its offset (0.25–0.75 V) and full-scale output (4.25–4.75 V) are pre-trimmed. While auto-zero functionality is supported via external firmware (see AN1636), it is not required for standard operation - the MPXV7002GC6U delivers specified accuracy without user intervention.
Can the MPXV7002GC6U be used with a 3.3 V microcontroller ADC?
The MPXV7002GC6U is specified for 4.75–5.25 V supply and produces a 0.25–4.75 V output. Direct interfacing with a 3.3 V ADC is not recommended due to output exceeding the ADC's input range and potential rail saturation. A precision resistive divider or rail-to-rail op-amp buffer is required to scale the MPXV7002GC6U output into the 0–3.3 V window while preserving linearity and noise performance.
What is the maximum pressure the MPXV7002GC6U can withstand without damage?
The MPXV7002GC6U has a maximum pressure rating of 75 kPa (absolute) - far exceeding its ±2.0 kPa operating range. This overpressure capability protects against transient spikes during installation or system faults. However, exposure beyond 75 kPa may cause permanent degradation, and operation outside the ±2.0 kPa range yields saturated (clamped) output, not valid measurement.
Is the MPXV7002GC6U compatible with non-dry-air media such as oxygen or nitrogen?
The MPXV7002GC6U is qualified and characterized using dry air as the pressure medium. Use with other gases (e.g., O₂, N₂) or liquids is not validated by NXP and may affect long-term reliability or accuracy due to fluorosilicone gel interaction or diaphragm stress. For non-dry-air applications, consult NXP's factory for media compatibility testing data before deploying the MPXV7002GC6U.
