Product details
Overview
MPXV53GC7U from Freescale Semiconductor is an uncompensated silicon piezoresistive pressure sensor with gauge configuration, 0–50 kPa full-scale range, ratiometric 3.0–6.0 V supply operation, and 60 mV typical full-scale output span. It delivers linear differential voltage output directly proportional to applied pressure and is designed for integration into external temperature compensation and signal conditioning networks in pneumatic and environmental control systems.
For engineers reviewing the MPXV53GC7U datasheet, MPXV53GC7U pinout, MPXV53GC7U application, or MPXV53GC7U equivalent, this page provides verified mechanical dimensions, confirmed pin functions, validated operating characteristics (including ±0.1%VFSS hysteresis and –0.22 to –0.16 %VFSS/°C TCVFSS), and two field-validated alternative part numbers for gauge-pressure sensing at 50 kPa range.
Technical Context
The MPXV53GC7U implements a patented single-element silicon shear-stress strain gauge integrated monolithically into a thin diaphragm, eliminating thermal expansion mismatch errors common in bonded gauges. Its ratiometric output ensures proportional scaling with supply voltage, simplifying ADC reference design.
It operates across –40°C to +125°C with specified offset stability of ±0.5%VFSS after 1000-hour pulsed pressure/temperature cycling, and exhibits 1.0 ms typical response time (10%–90%) - enabling real-time pressure monitoring in closed-loop pneumatic actuators and medical airflow systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0 to 50 kPa gauge - supports low-pressure pneumatic control and leak detection up to ~7.25 psi absolute differential. |
| Full-Scale Span | 45–90 mV (typ. 60 mV) - enables direct interface with 12-bit+ SAR ADCs without amplification in 3.3 V systems. |
| Supply Voltage | 3.0–6.0 VDC - ratiometric behavior allows shared VREF/VCC routing with microcontroller ADC. |
| Linearity Error | ±0.6% VFSS (end-point fit) - defines worst-case deviation from ideal transfer function over full scale. |
| Response Time | 1.0 ms (10%–90%) - suitable for dynamic pressure events such as valve actuation or airflow transients. |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, industrial HVAC, and portable medical equipment. |
| Offset Voltage | 0–35 mV at 0 kPa - requires external nulling or calibration in precision applications. |
Pinout & Package
MPXV53GC7U uses the unibody chip carrier package Case 98ASB14911C (gauge configuration), with stainless steel port attached on the P1 side and silicone gel isolation protecting the die. Dimensions: 29.08 × 17.40 × 4.62 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for both supply and output; notch-aligned pin 1 identification per JEDEC MO-152 variant. |
| 2 | +VOUT | Positive differential output terminal; voltage rises with increasing P1 pressure relative to P2 vacuum side. |
| 3 | VS | Supply input (3.0–6.0 VDC); powers Wheatstone bridge and sets output scale via ratiometric relationship. |
| 4 | –VOUT | Negative differential output terminal; completes bridge output pair - used with instrumentation amplifier for noise rejection. |
Key Features
| Feature | Design Value |
|---|---|
| Patented silicon shear-stress strain gauge | Monolithic integration eliminates thermal drift from CTE mismatch - critical for stable offset over –40°C to +125°C. |
| Ratiometric output | Output scales linearly with VS; removes need for separate precision voltage reference when sharing MCU VDD/VREF. |
| Unibody gauge package (98ASB14911C) | Stainless steel port on P1 side enables direct mounting to pressurized lines; silicone gel protects wire bonds from moisture and particulates. |
| Low hysteresis (±0.1%VFSS) | Ensures repeatable readings during cyclic pressure changes - essential for level sensing and closed-loop feedback control. |
Applications
| Medical Airflow Monitoring | Pneumatic Actuator Feedback |
|---|---|

IC Role / Device Role / Timing Role: Low-range pressure transducer interfaced to HVAC controller for fan speed modulation. Use Value: 0–50 kPa range matches typical duct pressure differentials (0.2–2.0 inH₂O), and unibody package resists condensation ingress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge-pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX53GP | Same die, identical 0–50 kPa gauge range, same 98ASB14911C package and pinout; MPXV53GC7U is legacy marking variant of MPX53GP. | No functional difference - MPX53GP is current production replacement with updated documentation and lifecycle support. | Select MPX53GP for new designs requiring active manufacturing status and long-term availability. |
| MPXV5050GP | Higher accuracy (±1.5% total error band vs. ±2.5% for MPXV53GC7U), integrated temperature compensation, 5 V supply only, same 4-pin SOIC footprint. | Eliminates need for external compensation circuitry but requires 5 V bias and offers no ratiometric flexibility. | Choose MPXV5050GP when system-level accuracy and reduced BOM count outweigh supply voltage and calibration flexibility requirements. |
Compared with MPX53GP, MPXV53GC7U shares identical electrical performance and mechanical form but lacks current production status; versus MPXV5050GP, it trades built-in compensation for ratiometric operation and wider supply range - favoring cost-sensitive, externally compensated designs.

FAQ
What is the pressure type and range supported by the MPXV53GC7U?
The MPXV53GC7U is a gauge pressure sensor with a full-scale range of 0 to 50 kPa. It measures pressure relative to ambient atmospheric pressure on the P2 (vacuum) side, with the P1 side exposed to the process pressure. This range corresponds to approximately 0–7.25 psi and is optimized for low-pressure pneumatic and environmental monitoring applications where high linearity and repeatability are required.
Does the MPXV53GC7U include internal temperature compensation?
No, the MPXV53GC7U is an uncompensated silicon pressure sensor. It requires external temperature compensation circuitry - such as resistor networks or microcontroller-based algorithms - to correct for offset and full-scale drift over temperature. Its design intentionally simplifies external compensation by leveraging predictable behavior from Freescale's monolithic shear-stress strain gauge architecture.
What package type and pin configuration does the MPXV53GC7U use?
The MPXV53GC7U uses the unibody chip carrier package Case 98ASB14911C, featuring a stainless steel port attached to the P1 side. It has a 4-pin configuration: Pin 1 = GND, Pin 2 = +VOUT, Pin 3 = VS (3.0–6.0 VDC), Pin 4 = –VOUT. The notch on the package identifies Pin 1, and the silicone gel encapsulation isolates the die while transmitting pressure.
Can the MPXV53GC7U be used with a 3.3 V microcontroller ADC system?
Yes, the MPXV53GC7U operates ratiometrically from 3.0 VDC, making it fully compatible with 3.3 V systems. Its typical 60 mV full-scale output spans 0–60 mV at 3.0 V supply, which maps cleanly to a 3.3 V ADC reference. For optimal SNR, use an instrumentation amplifier with gain (e.g., 50×) before the ADC to resolve sub-mV pressure steps without introducing supply noise coupling.
Is the MPXV53GC7U RoHS compliant and lead-free?
Yes, the MPXV53GC7U conforms to RoHS Directive 2011/65/EU and is lead-free. Freescale's MPX53 series packaging - including Case 98ASB14911C - uses matte tin lead finish and halogen-free molding compounds. Full compliance documentation, including test reports and material declarations, is available through NXP's product change notifications and quality portal for MPX53GP, the direct production successor to MPXV53GC7U.
