Product details
Overview
MPX53D from Freescale Semiconductor is a silicon piezoresistive differential pressure sensor with 0–50 kPa range, ratiometric 3.0–6.0 V supply operation, 60 mV typical full-scale span, and unibody package (Case 98ASB42280B). It delivers linear voltage output directly proportional to applied differential pressure and is used in pneumatic control systems requiring uncompensated analog sensing.
For engineers reviewing the MPX53D datasheet, MPX53D pinout, MPX53D application, or MPX53D equivalent, this page provides verified mechanical dimensions, temperature coefficients, offset stability, linearity error, and port-side identification for accurate integration into pressure-differential signal chains.
Technical Context
The MPX53D uses a patented transverse-voltage diffused silicon shear-stress strain gauge integrated monolithically into a thin diaphragm-eliminating thermal expansion mismatch errors common in bonded gauges. Its ratiometric output scales linearly with supply voltage, enabling direct interface with ADCs referenced to the same VS.
It operates over –40 °C to +125 °C with ±0.1%VFSS pressure hysteresis and ±0.5%VFSS temperature hysteresis. External temperature compensation is required for high-accuracy applications, as the device is intentionally uncompensated-allowing system-level calibration using resistive networks per AN840.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0 to 50 kPa differential (P1 > P2); defines usable sensing window without saturation or damage. |
| Full-Scale Span | 45–90 mV (typ. 60 mV) at VS = 3.0 V; determines raw ADC resolution and gain staging requirements. |
| Supply Voltage | 3.0–6.0 VDC; ratiometric behavior means output scales linearly with VS-critical for supply-referenced measurement systems. |
| Linearity Error | ±0.6%VFSS (end-point fit); sets worst-case deviation from ideal VOUT = VOFF + (1.2 mV/kPa × P) across full range. |
| Response Time | 1.0 ms (10%–90%); supports dynamic pressure monitoring in fast pneumatic or leak-detection cycles. |
| Offset Voltage | 0–35 mV at 0 kPa; requires system-level nulling or calibration to achieve zero-pressure baseline accuracy. |
| Input Impedance | 355–505 Ω; defines minimum drive capability needed from supply regulator or buffer stage. |
Pinout & Package
MPX53D is housed in a unibody chip carrier package (Case 98ASB42280B), stainless steel cap on P1 side, with silicone gel isolation of die and wire bonds. Pin 1 identified by notch; 4-pin DIP-compatible outline with 2.54 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Reference ground for both supply and output; must be low-impedance return path to avoid common-mode error. |
| 2 | +VOUT | Positive differential output terminal; voltage rises with increasing P1–P2 pressure difference. |
| 3 | VS | Excitation supply input (3.0–6.0 VDC); powers Wheatstone bridge and sets full-scale output scaling. |
| 4 | –VOUT | Negative differential output terminal; completes bridge output pair-enables true differential amplification. |
Key Features
| Feature | Design Value |
|---|---|
| Patented silicon shear-stress strain gauge | Monolithic integration eliminates thermal expansion mismatch-reducing drift vs. bonded-gauge sensors. |
| Ratiometric output | Output voltage scales precisely with VS, enabling supply-referenced ADC architectures without ratio-metric error correction. |
| Dual-port differential configuration | P1 (stainless cap) and P2 (vacuum side) enable bidirectional pressure difference sensing-critical for flow and leak detection. |
| Uncompensated architecture | Allows manufacturer-specific external temperature compensation and signal conditioning-maximizing design flexibility and cost control. |
| Low response time (1.0 ms) | Supports real-time closed-loop pneumatic control and transient pressure event capture without filtering delay. |
Applications
| Medical Instrumentation | Pneumatic Control Systems |
|---|---|

IC Role / Device Role / Timing Role: High-stability differential sensor comparing test volume to reference chamber pressure. Use Value: ±0.5%VFSS offset stability after 1000-hour stress testing ensures long-term calibration integrity-minimizing false positives. |
Use Scenario: Maintaining precise airflow balance in cleanroom ventilation by measuring static pressure across filters and dampers. IC Role / Device Role / Timing Role: Gauge-mode pressure monitor (P1 = duct, P2 = ambient) for fan speed modulation. Use Value: 0–50 kPa range matches typical HVAC differential pressures; stainless cap (P1 side) resists particulate contamination in duct environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar differential pressure transducer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX53DP | Dual-port configuration in Case 98ASB14912C; identical electrical specs but distinct port marking and mechanical mounting. | Designed for PCB-mount with labeled P1/P2 ports-better suited for automated assembly where orientation verification is critical. | Select MPX53DP when consistent port-side identification and SMT compatibility are required over the through-hole–optimized MPX53D. |
| MPX2053DP | Temperature-compensated version (–40 °C to +125 °C); includes on-chip compensation network-no external components needed. | Reduces design effort for wide-temperature industrial deployments but increases unit cost and removes calibration flexibility. | Choose MPX2053DP only when system-level temperature compensation is impractical and ±2%FS total error budget permits higher-cost pre-compensated solution. |
Compared with MPX53DP, MPX53D offers identical core sensing performance in a through-hole unibody package optimized for prototyping and serviceable installations; versus MPX2053DP, MPX53D trades off factory compensation for full external calibration control-enabling tighter system-level accuracy with custom compensation algorithms.

FAQ
What is the pressure port configuration of the MPX53D?
The MPX53D features a dual-port differential configuration: the stainless steel cap side is the Pressure (P1) port, and the opposite side is the Vacuum (P2) port. Per Freescale documentation, it is designed for P1 > P2 operation. The case number 98ASB42280B identifies this specific unibody package, and correct orientation is confirmed by the notch-aligned Pin 1 and cap-side labeling.
Does the MPX53D require external temperature compensation?
Yes, the MPX53D is explicitly an uncompensated sensor. Its temperature coefficient of full-scale span (–0.22 to –0.16 %VFSS/°C) and offset (±15 µV/°C) necessitate external compensation-typically via resistive networks or microcontroller-based algorithms. Application Note AN840 details proven methods for –40 °C to +125 °C compensation, and the MPX53D datasheet confirms no on-chip compensation circuitry is present.
What is the meaning of "ratiometric" for the MPX53D output?
"Ratiometric" means the MPX53D's output voltage scales linearly with its supply voltage (VS). For example, at 3.0 V supply, full-scale output is ~60 mV; at 6.0 V supply, it becomes ~120 mV-preserving proportionality. This allows direct connection to supply-referenced ADCs without additional gain calibration, as both reference and signal track VS variations simultaneously.
Can the MPX53D be used in gauge pressure mode?
No-the MPX53D is specified exclusively for differential pressure (P1–P2) operation. While Freescale's MPX53GP variant is designed for gauge use (P1 vs. atmospheric reference), the MPX53D lacks internal venting or packaging to reference ambient pressure. Using it as a gauge sensor would yield undefined output due to uncontrolled P2-side conditions.
What is the maximum burst pressure rating for the MPX53D?
The MPX53D has a specified burst pressure of 200 kPa (P1 > P2), beyond which permanent mechanical damage may occur. This exceeds its 175 kPa maximum operating pressure (PMAX) and provides a 4× safety margin over its 50 kPa full-scale range. Operation above PMAX risks diaphragm deformation or seal failure-even if below burst pressure-so system design must include pressure limiting.
