Product details
Overview
MPXC12DT1 from Freescale Semiconductor is a biocompatible, uncompensated silicon pressure sensor with a 10 kPa gauge pressure range, ratiometric output, and Chip Pak package (Case 98ASB13355C). It features a patented shear-stress strain gauge design, polysulfone housing compliant with ISO 10993, and operates at +15°C to +40°C for invasive medical applications.
For engineers reviewing the MPXC12DT1 datasheet, MPXC12DT1 pinout, MPXC12DT1 application, or MPXC12DT1 equivalent, key selection considerations include its backside-pressure architecture, exposed die requiring customer-side front-side protection, biocompatible housing without pre-applied gel, and need for external temperature compensation and signal conditioning.
Technical Context
The MPXC12DT1 implements a single-element silicon shear-stress strain gauge, enabling simplified external compensation due to minimal thermal drift coupling. Its ratiometric output (VS = 3–6 VDC) ensures proportional response to supply voltage changes, supporting stable analog signal chains in low-power medical systems.
Designed for differential pressure sensing with backside actuation, the device delivers 45–80 mV full-scale span and ±0.1%VFSS hysteresis over 0–10 kPa. Input impedance (400–550 Ω) and output impedance (750–1250 Ω) are optimized for direct interface with instrumentation amplifiers in disposable diagnostic modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–10 kPa gauge; supports respiratory diagnostics requiring precise low-range differential pressure measurement |
| Supply Voltage | 3–6 VDC; ratiometric operation enables stable output scaling with supply variations in battery-powered devices |
| Full-Scale Span | 45–80 mV; defines usable analog output swing for 10 kPa input, requiring ≥12-bit ADC resolution for ≤0.1 kPa accuracy |
| Offset Voltage | 0–35 mV at zero pressure; necessitates offset trimming or software calibration in final system design |
| Response Time | 1.0 ms (10%–90%); suitable for dynamic airway pressure monitoring in ventilators and spirometers |
| Operating Temp | +15°C to +40°C; validated for human-body-temperature environments in invasive blood pressure or catheter-based sensors |
| Package | Chip Pak, Case 98ASB13355C; white medical-grade polysulfone housing certified per ISO 10993-5/10/11 |
Pinout & Package
MPXC12DT1 uses a 4-pin Chip Pak surface-mount package (Case 98ASB13355C), with pressure applied to the backside and exposed die/wire bonds on the front side requiring customer-provided mechanical protection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Reference ground for supply and output; must be low-impedance to minimize noise in sensitive analog measurements |
| 2 | +VOUT | Positive differential output terminal; used with Pin 4 to extract bridge voltage across pressure-sensitive element |
| 3 | +VS | Excitation supply input; powers Wheatstone bridge; ratiometric output scales directly with this voltage |
| 4 | –VOUT | Negative differential output terminal; forms balanced pair with Pin 2 for noise-rejecting instrumentation amplifier interface |
Key Features
| Feature | Design Value |
|---|---|
| Ratiometric Output | Output voltage scales linearly with supply voltage (VS = 3–6 VDC), eliminating need for precision voltage references in portable medical devices |
| Biocompatible Housing | White polysulfone case meets ISO 10993-5/10/11 for cytotoxicity, sensitization, and hemolysis-enabling use in invasive blood pressure monitoring |
| Shear-Stress Strain Gauge | Single-element silicon design reduces thermal coefficient mismatch, simplifying external temperature compensation circuitry |
| No Pre-Applied Gel | Backside remains uncoated, allowing end-users to apply application-specific medical gels (e.g., ultrasound or ECG coupling media) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV5004DP | Compensated and amplified; 0–4 kPa range; integrated signal conditioning; SOIC-8 package | Targeted at non-invasive, lower-pressure applications (e.g., CPAP); not ISO 10993 certified | Choose MPXV5004DP only if external compensation and biocompatibility are unnecessary |
| NSPC1010DT1 | Same Chip Pak package and 10 kPa range; includes factory-applied medical gel; requires no user gel application | Pre-gelled version for rapid integration into disposable respiratory circuits where gel consistency is critical | Choose NSPC1010DT1 when gel application process control or shelf-life stability is required |
Compared with MPXV5004DP and NSPC1010DT1, the MPXC12DT1 uniquely balances biocompatibility, backside-pressure flexibility, and uncompensated architecture-making it optimal for OEMs designing custom-compensated, sterilizable, gel-customizable medical pressure modules.

FAQ
What is the pressure port configuration of the MPXC12DT1?
The MPXC12DT1 is a backside-pressure sensor: pressure is applied to the rear surface of the Chip Pak package, while the front side exposes the die and wire bonds. This architecture requires the customer to implement mechanical protection (e.g., conformal coating or housing) on the front side to prevent damage during handling or assembly. The device does not include gel on the backside, enabling application-specific gel selection.
Does the MPXC12DT1 require external temperature compensation?
Yes, the MPXC12DT1 is an uncompensated sensor. Its offset and span exhibit temperature dependence across the +15°C to +40°C operating range, so external compensation-via analog circuitry (e.g., thermistor networks) or digital correction (e.g., microcontroller lookup tables)-must be implemented. Freescale designed the single-element shear-stress gauge to simplify this compensation relative to multi-element bridges.
Is the MPXC12DT1 certified for medical use?
The MPXC12DT1 housing is molded from medical-grade polysulfone certified to ISO 10993-5 (cytotoxicity), ISO 10993-10 (sensitization), and ISO 10993-11 (hemolysis), making it suitable for invasive medical applications. However, final regulatory approval (e.g., FDA 510(k)) rests with the end-product manufacturer integrating the MPXC12DT1 into a complete system.
What is the maximum pressure rating for the MPXC12DT1?
The MPXC12DT1 has a maximum rated pressure of 75 kPa on the backside, well above its 10 kPa full-scale range. This overpressure capability provides safety margin against transient spikes in clinical environments, such as cough-induced airway pressure surges in ventilated patients.
Can the MPXC12DT1 be sterilized?
Yes, the MPXC12DT1 is compatible with ethylene oxide (EtO) sterilization, as confirmed by Freescale's biocompatibility testing. The polysulfone housing and internal silicon structure withstand standard EtO cycles without degradation. Autoclaving or gamma irradiation are not recommended and may damage the device.
