Product details
Overview
MPXV2050GP from NXP Semiconductors is a gauge-ported, temperature-compensated silicon piezoresistive pressure sensor delivering ratiometric voltage output proportional to applied pressure. It features 50 kPa full-scale range, ±0.3%VFSS linearity, and on-chip laser-trimmed calibration for offset and span across 0 °C to 85 °C. Used in medical diagnostics and robotics for precise differential pressure sensing with dry clean air media.
For engineers reviewing the MPXV2050GP datasheet, MPXV2050GP pinout, MPXV2050GP application, or MPXV2050GP equivalent, key selection criteria include its gauge port configuration, 4-pin SOIC package (Case 1369), ratiometric output behavior, temperature-compensated accuracy over industrial operating temperatures, and compatibility with low-noise analog signal chains requiring <1 ms response time.
Technical Context
The MPXV2050GP integrates a monolithic silicon diaphragm with embedded strain gauges and thin-film resistor networks, enabling direct voltage output without external signal conditioning. Its ratiometric architecture ties output scaling to supply voltage (VS = 10–16 Vdc), ensuring stability against excitation drift.
On-chip temperature compensation corrects both full-scale span (TCVFSS ±1.0 %VFSS) and offset (TCVoff ±1.0 mV) over 0 °C to 85 °C. The device operates with P1 > P2 differential pressure, where P1 is the gel-isolated port side identified by the physical port attachment on Case 1369 packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–50 kPa gauge range; supports non-invasive blood pressure measurement and pump control up to 7.25 PSI. |
| Output Type | Differential ratiometric voltage output (±VOUT); 40 mV full-scale span at VS = 10 Vdc enables high-resolution ADC interfacing. |
| Accuracy | ±0.3%VFSS linearity (end-point method); ±0.1%VFSS pressure hysteresis ensures repeatability in cycling applications like level indicators. |
| Temperature Compensation | Factory-calibrated over 0 °C to 85 °C; TCVFSS ±1.0 %VFSS and TCVoff ±1.0 mV minimize thermal drift in embedded medical or industrial environments. |
| Response Time | 1.0 ms (10%–90%); suitable for real-time closed-loop motor controllers and dynamic robotics feedback systems. |
| Supply Voltage | 10–16 Vdc; operation above 16 Vdc risks self-heating-induced error per datasheet specification. |
| Operating Temperature | −40 °C to +125 °C ambient; qualified for extended industrial use despite compensation limited to 0–85 °C. |
Pinout & Package
MPXV2050GP uses the Small Outline Package (SOT1693-3), Case 1369-01 - an 8-pin SOIC variant with 4 active terminals and 4 no-connect pins. The package includes a silicone-gel-isolated pressure port on the P1 side for environmental protection while transmitting pressure to the silicon diaphragm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Analog ground reference for output and supply return; must be low-impedance to maintain ratiometric accuracy. |
| 2 | +VOUT | Positive differential output terminal; delivers voltage proportional to pressure applied to P1 side relative to P2. |
| 3 | VS | Power supply input; ratiometric output scales directly with this voltage, requiring stable regulation for precision measurement. |
| 4 | –VOUT | Negative differential output terminal; completes the Wheatstone bridge output pair for noise-rejecting instrumentation amplifier interfaces. |
Key Features
| Feature | Design Value |
|---|---|
| Ratiometric Output | Output voltage scales linearly with supply voltage (VS), eliminating need for separate voltage reference in microcontroller-based readout circuits. |
| On-Chip Temperature Compensation | Compensates both offset and full-scale span over 0 °C to 85 °C using integrated thin-film resistors, reducing system-level calibration effort. |
| Gauge Port Configuration | P1 side has physical port for ambient pressure sensing; P2 side is sealed vacuum reference - ideal for barometric or fluid-level monitoring. |
| Laser-Trimmed Calibration | Factory laser trimming of span and offset achieves ±1.0 mV offset and ±0.3%VFSS linearity without external potentiometers or digital correction. |
| Low Response Time | 1.0 ms rise time enables integration into fast-cycling systems such as respiratory monitors and automated valve control loops. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV5050GC6U | Same 50 kPa range but in 6-pin SMT package (Case 476); includes internal voltage regulator and wider supply range (4.75–30 Vdc). | Designed for battery-powered devices needing wide-input regulation; lacks differential output - single-ended only. | Select MPXV5050GC6U when board space allows larger footprint and regulated supply simplifies power design. |
| MPXH6115A | 115 kPa range, 10–16 Vdc supply, same Case 1369 package; higher full-scale span (80 mV) and ±0.5%VFSS linearity. | Targeted at higher-pressure HVAC and industrial process control; not drop-in due to different pressure range and calibration. | Choose MPXH6115A only if system requires >50 kPa headroom and can accommodate recalibration of signal chain gain. |
Compared with MPXV2050GP, MPXV5050GC6U offers supply flexibility at the cost of differential output and increased footprint, while MPXH6115A trades resolution and linearity for extended pressure range - neither is pin-compatible, and both require PCB layout and firmware adjustments.

FAQ
What is the pressure port configuration of the MPXV2050GP?
The MPXV2050GP is a gauge pressure sensor with a single port on the P1 side (identified by the physical port attachment on Case 1369 packaging) and a sealed vacuum reference on the P2 side. It measures pressure relative to ambient atmosphere, making it suitable for level indicators and non-invasive blood pressure applications where atmospheric reference is required. The MPXV2050GP must be mounted with the port facing the measured medium and the vacuum side isolated from pressure exposure.
Does the MPXV2050GP require external signal conditioning?
No, the MPXV2050GP provides a fully conditioned, ratiometric differential voltage output that can be directly interfaced with instrumentation amplifiers or delta-sigma ADCs. Its on-chip laser trimming and temperature compensation eliminate the need for external offset or span adjustment circuitry. However, proper PCB layout - including Kelvin connections for VS and GND, and shielding for ±VOUT - is essential to preserve the specified ±0.3%VFSS linearity and ±0.1%VFSS hysteresis in the final MPXV2050GP implementation.
What is the maximum overpressure rating for the MPXV2050GP?
The MPXV2050GP has a maximum overpressure rating of 200 kPa under P1 > P2 conditions, as specified in Table 3 of the datasheet. Exceeding this limit may cause permanent mechanical deformation of the silicon diaphragm or degradation of calibration accuracy. This rating supports robust operation in pump/motor controller applications where transient pressure spikes occur, but sustained operation above 50 kPa will not yield valid measurements and should trigger system-level fault handling in designs using the MPXV2050GP.
Can the MPXV2050GP operate with supply voltages below 10 Vdc?
No - the MPXV2050GP is characterized and guaranteed only for supply voltages between 10 Vdc and 16 Vdc, as stated in Table 4. Operation below 10 Vdc falls outside the specified excitation range and may result in reduced output span, increased nonlinearity, or failure to meet the ±1.0 mV offset specification. The MPXV2050GP's ratiometric behavior means output scales linearly with VS, so lowering supply voltage proportionally reduces sensitivity (e.g., ~0.8 mV/kPa at 10 Vdc becomes ~0.4 mV/kPa at 5 Vdc), but this is not validated or supported by NXP.
Is the MPXV2050GP compatible with media other than dry clean air?
The MPXV2050GP's qualification and reliability testing are based exclusively on dry clean air as the pressure medium. Use with other gases or liquids - including moisture, oils, or corrosive vapors - may degrade long-term performance or cause irreversible damage to the silicone gel isolation or wire bonds. NXP explicitly advises contacting factory support before deploying the MPXV2050GP in non-air media; application note AN3728 provides further guidance on media compatibility limits for the MPXV2050GP and related variants.
