Product details
Overview
MPX2050GSX from Freescale Semiconductor is a gauge-pressure silicon piezoresistive sensor with on-chip temperature compensation and laser-trimmed calibration, delivering 40 mV full-scale output at 10 V supply across 0–50 kPa range, ±0.25% linearity (end-point method), and 1.0 ms response time for medical diagnostics and pump control applications.
For engineers reviewing the MPX2050GSX datasheet, MPX2050GSX pinout, MPX2050GSX application, or MPX2050GSX equivalent, this page provides verified technical context, package-validated pin functions, real-world use cases in non-invasive blood pressure monitoring and robotics, and two confirmed alternative sensors with documented parameter and interface differences.
Technical Context
The MPX2050GSX integrates a monolithic silicon diaphragm with embedded strain gauges and thin-film resistor networks for ratiometric voltage output proportional to applied gauge pressure (P1 relative to ambient). Its on-chip circuitry performs laser-trimmed span/offset calibration and temperature compensation over –40°C to +125°C operating range.
It operates with 10 Vdc excitation (up to 16 Vdc max), draws 6.0 mA typical supply current, and features 1400–3000 Ω output impedance. The device uses dry air as validated pressure media; alternate media require factory consultation due to potential long-term reliability impact.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0 to 50 kPa gauge - supports medical BP measurement up to 7.25 psi and industrial level sensing within standard atmospheric reference. |
| Full Scale Span | 38.5–41.5 mV at 10 V supply - enables direct ADC interfacing with 12-bit resolution without amplification in many embedded systems. |
| Linearity Error | ±0.25% VFSS (end-point method) - ensures predictable error budget for closed-loop motor/pump controllers requiring repeatable pressure thresholds. |
| Response Time | 1.0 ms (10% to 90%) - suitable for dynamic pressure events in robotics actuation and rapid pressure switching circuits. |
| Temperature Range | –40°C to +125°C operating - allows deployment in under-hood automotive subsystems and sterilizable medical enclosures. |
| Supply Voltage | 10 Vdc typical, 16 Vdc max - ratiometric output eliminates need for precision voltage reference when using same supply for ADC reference. |
| Offset Voltage | –1.0 to +1.0 mV at zero pressure - simplifies offset nulling in low-cost signal chains without trimming components. |
Pinout & Package
MPX2050GSX uses Case 344F-01 unibody chip carrier package: 4-pin, surface-mount, stainless steel cap with port attached to P1 side, silicone gel isolation, and epoxy-sealed die. Dimensions: 29.08–29.85 mm × 17.40–18.16 mm × 7.75–8.26 mm (L×W×H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | GND | Ground reference for both supply and output; must be low-impedance connection to minimize common-mode noise in differential output path. |
| Pin 2 | V(–) OUT | Negative output terminal of differential pair; used with Pin 4 to reject common-mode supply ripple and thermal drift. |
| Pin 3 | VS | Positive supply input (10 Vdc typical); ratiometric output scales linearly with this voltage-critical for accuracy when shared with ADC reference. |
| Pin 4 | V(+) OUT | Positive output terminal; output voltage increases with pressure applied to P1 port relative to ambient (gauge configuration). |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Validated over 0°C to +85°C - eliminates external thermistor network and reduces BOM count in portable medical devices. |
| Monolithic silicon shear-stress strain gauge | Higher sensitivity stability vs. traditional piezoresistive elements - maintains ±0.1% pressure hysteresis over 0–50 kPa cycling. |
| Ratiometric output | Output scales directly with supply voltage - enables single-supply operation with shared 10 V rail for sensor and 10-bit+ SAR ADC without gain calibration. |
| Laser-trimmed calibration | Factory-set span and offset - removes need for end-of-line trimming in high-volume pump controller manufacturing. |
| Gauge pressure configuration | P1 port referenced to ambient - simplifies mechanical integration in level indicators and non-invasive blood pressure cuffs without vacuum lines. |
Applications
| Non-Invasive Blood Pressure Monitoring | Pump/Motor Controllers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV5004GP | 4.5–5.5 V supply, 0.25–0.75 V ratiometric output, 2.5 kPa to 4 kPa range, integrated signal conditioning. | Lower voltage, lower pressure range; suited for battery-powered IoT nodes-not direct replacement for 50 kPa medical use. | Select MPXV5004GP only when system operates below 5.5 V and requires integrated op-amp output stage. |
| SPX301DN | 0–100 kPa range, 0.5–4.5 V analog output, 3.3 V supply, built-in ADC interface; no differential output. | Single-ended output, wider range, digital-ready interface; lacks MPX2050GSX's differential noise rejection and laser-trimmed calibration. | Choose SPX301DN when replacing legacy 0–100 kPa systems with 3.3 V microcontrollers and no analog front-end redesign. |
Compared with MPX2050GSX, MPXV5004GP offers lower power but narrower range and no differential output, while SPX301DN provides wider range and digital compatibility at the cost of reduced noise immunity and calibration precision-making MPX2050GSX optimal for high-accuracy analog gauge sensing at 50 kPa.

FAQ
What is the pressure type and reference for MPX2050GSX?
The MPX2050GSX is a gauge pressure sensor: it measures pressure at the P1 port relative to ambient atmospheric pressure at the P2 side. Per Freescale documentation, the P1 side is identified by the port attachment on Case 344F-01, and the device is rated for 0–50 kPa gauge range. It is not suitable for absolute or differential configurations without mechanical adaptation.
Does MPX2050GSX require external temperature compensation?
No, MPX2050GSX includes on-chip temperature compensation validated over 0°C to +85°C, with specified TCspan (±1.0%VFSS) and TCVoff (±1.0 mV) across –40°C to +125°C. Freescale's datasheet confirms full calibration-including span, offset, and thermal drift-is performed at wafer level using laser trimming, eliminating need for external thermistors or software correction in most applications.
What is the correct pinout configuration for MPX2050GSX?
Per Freescale Rev 9 datasheet, MPX2050GSX (Case 344F-01) uses Style 1 pinout: Pin 1 = GND, Pin 2 = V(–) OUT, Pin 3 = VS, Pin 4 = V(+) OUT. This matches the unibody package drawing and Figure 1 schematic. Output polarity is such that V(+) OUT rises with increasing pressure on the P1 port.
Can MPX2050GSX be used with media other than dry air?
Freescale explicitly states that MPX2050GSX operating characteristics and qualification testing are based on dry air. Use with other media-including moisture, oils, or corrosive gases-may degrade long-term reliability or cause irreversible damage. The datasheet directs users to contact Freescale/NXP factory for media compatibility validation before deployment in non-dry-air environments.
What is the maximum overpressure rating for MPX2050GSX?
The MPX2050GSX has a maximum pressure rating of 200 kPa (P1 > P2), per Table 2 Maximum Ratings in the Freescale datasheet. Exceeding this limit-even momentarily-may cause permanent damage or calibration shift. For applications with pressure spikes, external mechanical limiters or snubbers are recommended to protect the sensor diaphragm.
