Product details
Overview
MPX2050D from Freescale Semiconductor is a silicon piezoresistive differential pressure sensor with on-chip temperature compensation and laser-trimmed calibration, delivering 40 mV full-scale output at 10 V supply, ±0.25% linearity over 0–50 kPa range, and operation from –40°C to +125°C. It serves as a primary analog pressure transducer in medical diagnostics, pump controllers, and robotics where stable ratiometric output and minimal thermal drift are required.
For engineers reviewing the MPX2050D datasheet, MPX2050D pinout, MPX2050D application, or MPX2050D equivalent, this page provides verified package mapping (Case 344-15), terminal roles, calibrated performance metrics, and validated alternatives for gauge-pressure sensing systems requiring dry-air media compatibility and sub-millisecond response.
Technical Context
The MPX2050D integrates a monolithic silicon diaphragm with embedded strain gauges and thin-film resistor networks for direct pressure-to-voltage conversion. Its ratiometric architecture ensures output scaling with supply voltage, while on-chip circuitry delivers temperature-compensated span and offset across 0°C to +85°C.
Designed for differential pressure measurement (P1 > P2), the device uses a stainless steel cap to identify the pressure side and features silicone gel isolation of the die surface. It exhibits 1.0 ms response time (10–90%), <±0.1%VFSS pressure hysteresis, and ±0.5%VFSS offset stability after 1000-hour pulsed pressure/temperature cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0 to 50 kPa - supports non-invasive blood pressure monitoring and low-range industrial level sensing. |
| Full Scale Span | 40 mV (typ) at 10 V supply - enables direct ADC interfacing without gain stages in 12-bit+ systems. |
| Linearity Error | ±0.25% VFSS (end-point method) - ensures predictable error budgeting in closed-loop control feedback paths. |
| Supply Voltage | 10 Vdc (typ), up to 16 Vdc - allows operation from standard industrial rails with self-heating managed below 16 V. |
| Response Time | 1.0 ms (10% to 90%) - suitable for dynamic pressure events in motor/pump transient detection. |
| Temperature Range | –40°C to +125°C operating - qualified for under-hood automotive and industrial ambient environments. |
| Output Impedance | 1400–3000 Ω - compatible with standard op-amp buffer inputs without loading-induced gain error. |
Pinout & Package
MPX2050D is housed in the unibody Case 344-15 package: 4-pin, through-hole, stainless steel cap on pressure side, silicone gel-isolated die, epoxy-sealed lead frame. Dimensions: 15.11–16.00 mm (A), 13.06–13.56 mm (B), 5.08–5.59 mm (C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Reference ground for both supply and output; must be low-impedance to minimize common-mode error. |
| 2 | +VOUT | Positive differential output; voltage increases linearly with P1–P2 pressure difference. |
| 3 | VS | Positive supply input; ratiometric output scales directly with this rail (10 V typical). |
| 4 | –VOUT | Negative differential output; used with +VOUT to reject common-mode noise in instrumentation amps. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Calibrated over 0°C to +85°C - eliminates need for external thermistor networks or digital correction in analog signal chains. |
| Silicon shear-stress strain gauge | Monolithic diaphragm design - improves long-term stability vs. bonded foil gauges and reduces hysteresis to ±0.1%VFSS. |
| Ratiometric output | Output scales with VS - enables direct connection to same supply as ADC reference, canceling rail variation errors. |
| Dual-port differential configuration | P1 (stainless cap) / P2 (marked side) - supports true differential pressure measurement with vacuum-referenced or vented gauge modes. |
| Laser-trimmed calibration | Factory-set span and offset - guarantees 40 mV FS and <±1.0 mV offset without user trimming or calibration firmware. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Honeywell ASDXRRX005PDAA5 | 5 V ratiometric, I²C digital output, 0–5 psi range, integrated ADC - no analog signal conditioning needed but requires MCU firmware support. | Targets digital BOMs with space-constrained PCBs; lacks analog output flexibility for legacy analog-only systems. | Select when migrating from analog to digital interfaces and board area is critical; not drop-in for MPX2050D analog signal paths. |
| TE Connectivity MS5837-02BA | 0–2 bar absolute pressure, SPI/I²C, 24-bit resolution, built-in temperature compensation - higher precision but absolute (not differential) reference. | Used in underwater depth sensing and altimeters; requires vacuum reference port modification to emulate differential behavior. | Choose for high-resolution absolute pressure needs; MPX2050D remains preferred for true differential or gauge configurations with analog output. |
Compared with Honeywell ASDXRRX005PDAA5 and TE MS5837-02BA, the MPX2050D offers proven analog ratiometric output, stainless-steel port identification, and factory-calibrated linearity - making it optimal for cost-sensitive, analog-centric designs where digital bus overhead or absolute-reference constraints are prohibitive.

FAQ
What is the pressure port configuration of the MPX2050D?
The MPX2050D is a differential pressure sensor with two ports: P1 (pressure side) identified by the stainless steel cap per Table 3, and P2 (vacuum side) located opposite. It operates with P1 > P2 and is not rated for absolute or sealed-gauge use without hardware adaptation. The MPX2050D datasheet specifies dry air as the validated pressure media.
Does the MPX2050D require external temperature compensation?
No - the MPX2050D includes on-chip temperature compensation circuitry calibrated over 0°C to +85°C, eliminating the need for external thermistors or digital correction algorithms. Its TCspan is ±1.0%VFSS and TCVoff is ±1.0 mV over that range, as confirmed in Table 1 of the Freescale MPX2050D datasheet Rev 9.
What is the output type and drive capability of the MPX2050D?
The MPX2050D provides a differential analog voltage output (+VOUT and –VOUT) with 40 mV full-scale span at 10 V supply. Its output impedance is 1400–3000 Ω, requiring an instrumentation amplifier or high-input-impedance buffer stage before ADC sampling. It cannot directly drive loads below 10 kΩ without gain error.
Can the MPX2050D be used in absolute pressure measurement?
No - the MPX2050D is specified only for differential or gauge pressure measurement. Its internal structure and calibration assume P2 is either vented (gauge) or connected to a reference vacuum (differential). Absolute pressure measurement requires a dedicated absolute sensor such as the MPX5700 series, not the MPX2050D.
What is the maximum overpressure rating for the MPX2050D?
The MPX2050D has a maximum pressure rating of 200 kPa (P1 > P2), as stated in Table 2 of the datasheet. Exceeding this may cause permanent damage. This 4× overpressure margin supports surge tolerance in pump startup/shutdown events but does not extend calibration validity beyond 50 kPa full scale.
