Product details
Overview
MPXV7002DPT1 from NXP Semiconductors is a monolithic silicon differential pressure sensor 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 applied pressure (±2.0 kPa), operates from 4.75–5.25 V supply, and draws ≤10 mA - designed for microcontroller-based respiratory monitoring and HVAC control systems.
For engineers reviewing the MPXV7002DPT1 datasheet, MPXV7002DPT1 pinout, MPXV7002DPT1 application, or MPXV7002DPT1 equivalent, key selection criteria include its ±2.0 kPa differential range, SO8 SOT1693-1 surface-mount package, 1.0 ms response time, ±2.5% VFSS accuracy, and compatibility with standard ADC interfaces in medical and industrial sensing designs.
Technical Context
The MPXV7002DPT1 integrates a patented silicon shear-stress strain gauge with thin-film metallization and bipolar signal conditioning circuitry on a single die. Its architecture includes two gain stages, temperature compensation networks, and ground reference shift circuitry - all optimized for stable analog output under mechanical stress and thermal drift.
It implements a ratiometric transfer function Vout = VS × (0.2 × P(kPa) + 0.5) ±6.25% VFSS, where output scales linearly with both supply voltage and pressure. The device requires no external zeroing or calibration and uses dry air as the validated pressure medium; fluorosilicone gel isolates the die while transmitting pressure to the diaphragm.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | ±2.0 kPa differential - supports bidirectional airflow sensing in ventilators and filter monitoring. |
| Output Voltage | 0.25–4.75 V at 5.0 V supply - full-scale span of 4.0 V enables high-resolution 12-bit+ ADC digitization. |
| Accuracy | ±2.5% VFSS over +10 °C to +60 °C - includes linearity, TcOffset, TcSpan, and hysteresis error budget. |
| Response Time | 1.0 ms (10%–90%) - suitable for dynamic pressure events in breathing cycle detection. |
| Supply Voltage | 4.75–5.25 V DC - ratiometric operation ensures output stability against supply ripple. |
| Operating Temp | +10 °C to +60 °C - validated for hospital bed and HVAC ambient environments. |
| Max Pressure | 75 kPa absolute - provides robust overpressure protection without damage. |
Pinout & Package
MPXV7002DPT1 uses the SOT1693-1 thermoplastic SO8 package (12.06 mm × 12.06 mm × 7.62 mm), with 2.54 mm pitch and notch-marked pin 1. Pins 1, 5–8 are internal no-connects; only pins 2 (Vs), 3 (GND), and 4 (Vout) are externally usable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | No Connect | Internally unconnected - must remain floating per datasheet; not for grounding or routing. |
| Pin 2 | Supply Voltage (Vs) | 4.75–5.25 V DC input - requires 1.0 µF + 0.01 µF decoupling per Figure 6 to meet spec. |
| Pin 3 | Ground (GND) | Reference return path - must be low-impedance and separate from digital ground to avoid noise coupling. |
| Pin 4 | Voltage Output (Vout) | Analog output (0.25–4.75 V) - directly interfaces to MCU ADC; 0.1 mA source capability limits trace length. |
| Pins 5–8 | No Connect | All internally unconnected - must be left open; soldering or routing causes functional risk. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip signal conditioning | Eliminates external op-amps and ADC reference buffers - reduces BOM count and layout area by >3 components. |
| Temperature compensation | Validated across +10 °C to +60 °C - removes need for software lookup tables or external thermistors in medical devices. |
| Differential configuration | Two isolated ports (P1/P2) - enables true differential pressure measurement without common-mode offset errors. |
| Patented shear-stress gauge | Monolithic silicon construction - improves long-term stability and reduces sensitivity to mounting stress vs. piezoresistive bridges. |
| Ratiometric output | Output scales with Vs - allows use of same supply for sensor and ADC, simplifying power design and improving noise immunity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV5004DP | Wider ±4 kPa range, higher 10 mV/kPa sensitivity, but ±5% VFSS accuracy and no factory auto-zero. | Better suited for industrial process control with larger pressure excursions; less ideal for clinical breath timing. | Select MPXV5004DP only if ±4 kPa range is required and system-level calibration is feasible. |
| SDP3x-D-001D | MEMS-based, I²C digital output, ±125 Pa resolution, 0.1% FS accuracy, but requires external MCU firmware support. | Preferred for IoT-connected HVAC nodes needing digital telemetry; lacks analog simplicity of MPXV7002DPT1. | Choose SDP3x-D-001D when digital communication, ultra-high resolution, or energy harvesting compatibility is mandatory. |
Compared with MPXV7002DPT1, MPXV5004DP trades accuracy for extended range and MPXV7002DPT1 offers plug-and-play analog integration unmatched by SDP3x-D-001D's digital dependency - making MPXV7002DPT1 optimal for cost-sensitive, analog-centric medical and HVAC designs requiring rapid time-to-market.

FAQ
What is the pressure port configuration of the MPXV7002DPT1?
The MPXV7002DPT1 is a dual-port differential pressure sensor with distinct P1 (pressure side, marked side) and P2 (vacuum side) ports. Per Table 6, the P1 side is identified by the part marking on the SOT1693-1 package. It uses dry air as the validated pressure medium; contact NXP before using other media. The MPXV7002DPT1 does not support gauge or absolute configurations - only differential.
Does the MPXV7002DPT1 require external calibration or zeroing?
No, the MPXV7002DPT1 is factory-calibrated and temperature-compensated, with no external zeroing required for standard operation. Its offset is specified as 0.25–0.75 V at minimum pressure, and full-scale output is 4.25–4.75 V at ±2.0 kPa. Auto-zero functionality is optional and only recommended if ambient temperature changes exceed ±5 °C between zeroing and measurement - detailed in AN1636. The MPXV7002DPT1 delivers ready-to-use analog output.
What decoupling network is required for stable operation of the MPXV7002DPT1?
The MPXV7002DPT1 requires the decoupling network shown in Figure 6: a 1.0 µF bulk capacitor, 0.01 µF ceramic capacitor, and 470 pF filter capacitor between Vs and GND. This configuration suppresses supply noise and ensures output stability within ±2.5% VFSS accuracy. Omitting any of these capacitors risks violating operating characteristics, especially response time and warm-up time (20 ms). The MPXV7002DPT1's performance is validated only with this exact decoupling setup.
Can the MPXV7002DPT1 be used in absolute or gauge pressure configurations?
No - the MPXV7002DPT1 is exclusively a differential pressure sensor. Its ordering code "DP" denotes dual-port differential configuration. The MPXV7002GC and MPXV7002GP variants support gauge configurations, but they use different packages (SOT1854-1 and SOT1693-3) and pinouts. Substituting MPXV7002DPT1 into a gauge or absolute design will result in incorrect or non-functional output. Always match the suffix: DP = differential, GC/GP = gauge.
What is the maximum overpressure rating for the MPXV7002DPT1?
The MPXV7002DPT1 has a maximum pressure rating of 75 kPa (absolute) on either port - meaning it withstands up to 75 kPa differential pressure without permanent damage or performance degradation. This rating applies regardless of polarity (P1 > P2 or P2 > P1). Exceeding 75 kPa may cause irreversible diaphragm deformation. The MPXV7002DPT1's specified operating range remains ±2.0 kPa; overpressure tolerance is purely mechanical survival margin, not functional range.
