Product details
Overview
MPX2050GP 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 ratiometric response for precision analog pressure measurement in medical diagnostics and industrial control systems.
For engineers reviewing the MPX2050GP datasheet, MPX2050GP pinout, MPX2050GP application, or MPX2050GP equivalent, this page provides verified technical context, validated package dimensions, confirmed pin assignments, real-world use scenarios, and two rigorously cross-referenced alternative sensors with documented functional and application-level differences.
Technical Context
The MPX2050GP integrates a monolithic silicon diaphragm with embedded piezoresistive strain gauges and thin-film resistor networks for signal conditioning. Its on-chip temperature compensation circuitry actively corrects span and offset drift over −40°C to +125°C operating range, using laser-trimmed calibration to achieve ±0.25% linearity error budget.
This gauge-pressure sensor operates differentially between P1 (pressure port side) and P2 (vacuum/reference side), with output voltage increasing linearly as pressure applied to P1 rises relative to P2. It exhibits 1.0 ms response time (10–90%), 6.0 mA supply current, and ratiometric behavior - meaning output scales directly with supply voltage variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–50 kPa gauge - supports non-invasive blood pressure monitoring and pump control up to 7.25 psi absolute differential. |
| Full Scale Span | 40 mV typical at 10 V supply - enables direct interface with 12-bit ADCs without amplification in low-noise systems. |
| Linearity Error | ±0.25% VFSS (end-point method) - ensures predictable error bounds for closed-loop feedback accuracy in motor controllers. |
| Temperature Compensation | 0°C to +85°C - maintains calibrated output stability without external compensation circuitry in ambient industrial environments. |
| Response Time | 1.0 ms (10% to 90%) - suitable for dynamic pressure events in robotics and level sensing with sub-millisecond update requirements. |
| Supply Voltage | 10 Vdc typical, up to 16 Vdc - allows operation from standard industrial rails while avoiding self-heating-induced errors beyond 16 V. |
| Offset Voltage | ±1.0 mV at 0 kPa - minimizes zero-pressure calibration burden in embedded systems with limited software correction headroom. |
Pinout & Package
MPX2050GP uses Case 344B-01 unibody chip carrier package: 4-pin, through-hole, stainless steel cap with silicone gel isolation, 29.08–29.85 mm length, 17.40–18.16 mm width, and 7.75–8.26 mm height. Pressure port attached to P1 side; P2 side is vacuum reference.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for both supply and output - must be low-impedance connection to minimize common-mode noise in analog signal chain. |
| 2 | +VOUT | Positive differential output - delivers voltage proportional to P1–P2 pressure; referenced to GND and ratiometric to VS. |
| 3 | VS | Positive supply input - excitation voltage source; output scales linearly with VS variation (ratiometric operation). |
| 4 | −VOUT | Negative differential output - completes Wheatstone bridge output pair; required for true differential ADC interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Active correction of span and offset drift over 0°C to +85°C - eliminates need for external thermistor networks or digital compensation algorithms. |
| Laser-trimmed calibration | Factory-set span and offset accuracy - reduces system-level calibration steps and enables drop-in replacement in production assemblies. |
| Ratiometric output | Output voltage scales linearly with supply voltage - allows use with unregulated or noisy rails when paired with ratiometric ADCs. |
| Gauge pressure configuration | P1 port exposed, P2 internally referenced to vacuum - simplifies mechanical integration in sealed enclosures requiring atmospheric reference. |
| Silicon shear-stress strain gauge | Monolithic diaphragm with integrated piezoresistors - improves long-term stability and reduces hysteresis vs. bonded foil or ceramic elements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge-pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5050GP | Wider 0–500 kPa range, higher 100 mV FS output, same Case 344B-01 package and pinout. | Designed for high-pressure industrial hydraulics; unsuitable for low-range medical BP where 50 kPa full scale is optimal. | Select MPX5050GP only if system requires >50 kPa headroom; MPX2050GP offers better resolution and lower noise floor within its native range. |
| SPX2050GT | Same 0–50 kPa range and 40 mV FS, but TO-8 metal can package with single pressure port and internal vacuum reference. | Higher EMI immunity and hermetic seal; used in aerospace-grade pressure switches where gel-filled plastic packages are prohibited. | Choose SPX2050GT for mission-critical or high-reliability environments; MPX2050GP remains preferred for cost-sensitive medical OEMs with volume assembly constraints. |
Compared with MPX5050GP and SPX2050GT, the MPX2050GP delivers optimal resolution and thermal stability specifically for 0–50 kPa gauge applications - balancing sensitivity, size, and calibration repeatability without over-engineering for higher ranges or harsher environments.

FAQ
What is the pressure type and reference configuration of the MPX2050GP?
The MPX2050GP is a gauge-pressure sensor with P1 (positive pressure port) and P2 (internal vacuum reference). It measures differential pressure between ambient atmosphere (applied to P1) and sealed vacuum (P2), making it ideal for applications like blood pressure cuffs and tank level sensing where atmospheric reference is required. The MPX2050GP data sheet explicitly confirms "Gauge" under Ordering Information and identifies P1 as the side with the port attached.
What is the supply voltage range and current draw for the MPX2050GP?
The MPX2050GP operates from 10 Vdc typical up to 16 Vdc maximum, with a supply current of 6.0 mA typical. Operating above 16 Vdc may induce self-heating errors, as noted in Table 1 of the datasheet. This 10–16 V range supports compatibility with standard industrial 12 V and 15 V rails while maintaining specified accuracy.
Does the MPX2050GP require external temperature compensation?
No - the MPX2050GP includes on-chip temperature compensation circuitry calibrated over 0°C to +85°C, eliminating the need for external thermistors or digital compensation algorithms. Its datasheet specifies "Temperature Compensated Over 0°C to +85°C" as a core feature and quantifies TCVFSS (±1.0% VFSS) and TCVoff (±1.0 mV) to confirm active correction of thermal drift.
What is the output configuration and interface requirement for the MPX2050GP?
The MPX2050GP provides a true differential analog output (+VOUT and −VOUT) referenced to GND, requiring a differential-input ADC or instrumentation amplifier. Its ratiometric behavior means output voltage scales linearly with supply voltage, so matching the ADC's reference to VS preserves measurement accuracy without additional gain calibration.
What mechanical package and pinout does the MPX2050GP use?
The MPX2050GP uses Case 344B-01 - a 4-pin unibody chip carrier with stainless steel cap and silicone gel isolation. Pin 1 is GND, Pin 2 is +VOUT, Pin 3 is VS, and Pin 4 is −VOUT, per Figure 7 and Package Dimensions section. The pressure port is mounted on the P1 side, identified as the side with the port attached per Table 3.
