Product details
Overview
MPXV4006GC7U from Freescale Semiconductor is a monolithic silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and factory calibration. It delivers a ratiometric 0.2–4.7 V analog output across a 0–6 kPa (0–0.87 psi) gauge pressure range, operates from 4.75–5.25 V supply, consumes ≤10 mA, and achieves ±5.0% full-scale span accuracy over 10°C to 60°C - ideal for microcontroller-based medical airflow monitoring and HVAC differential pressure sensing.
For engineers reviewing the MPXV4006GC7U datasheet, MPXV4006GC7U pinout, MPXV4006GC7U application, or MPXV4006GC7U equivalent, key selection considerations include its side-port configuration (Case 482C-03), N/C pin layout, ratiometric transfer function (Vout = VS × [(0.1533×P) + 0.045]), and requirement for post-installation auto-zeroing to meet specified accuracy.
Technical Context
The MPXV4006GC7U integrates a shear-stress strain gauge, thin-film temperature compensation network, dual-stage gain amplification, and ground-reference shift circuitry onto a single die. Its output is inherently ratiometric to supply voltage, enabling direct interface with microcontroller ADCs without external reference voltage.
It uses fluorosilicone gel encapsulation to isolate the die while transmitting pressure to the silicon diaphragm, and is qualified for dry air media only. The device requires no external zeroing components but mandates system-level auto-zeroing at installation to compensate for mechanical stress-induced offset drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–6 kPa gauge - supports low-differential applications such as respiratory flow sensing and filter clog detection. |
| Output Voltage | 0.2–4.7 V (ratiometric to VS) - directly compatible with 5 V ADC references without scaling. |
| Supply Voltage | 4.75–5.25 V DC - tight tolerance ensures stable excitation for ±5% FSS accuracy. |
| Sensitivity | 766 mV/kPa typical - enables high-resolution pressure measurement within the 6 kPa range. |
| Operating Temp | −10°C to +60°C - validated for indoor environmental control and portable medical devices. |
| Accuracy | ±5.0% VFSS (10–60°C) - includes linearity, TcSpan, TcOffset, hysteresis, and stability after 1000 thermal cycles. |
| Max Pressure | 24 kPa - provides 4× overpressure margin for transient surge protection in duct systems. |
Pinout & Package
MPXV4006GC7U uses Case 482C-03: small-outline through-hole package with side-mounted pressure port and stainless-steel cap on P2 side. Dimensions: 10.79 × 10.79 × 6.48 mm (L×W×H), 8-pin lead frame, 2.54 mm pin pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect | Internal connection; must remain unconnected to avoid interference or damage. |
| 2 | Supply Voltage (VS) | 5 V DC input; ratiometric reference for output stage - decoupling (1 µF + 0.01 µF) required per Figure 3. |
| 3 | Ground (GND) | Analog ground reference for signal chain - must tie to clean system AGND, separate from digital ground. |
| 4 | Output (Vout) | Analog voltage output proportional to pressure - routed to MCU ADC with minimal trace length and shielding. |
| 5–8 | No Connect | All internal; floating pins - no PCB routing or soldering permitted. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Validated over 10°C to 60°C - eliminates need for external thermistor networks or software correction tables. |
| Factory-calibrated full-scale span | 4.6 V typical VFSS at 6 kPa - reduces production calibration time and test fixture complexity. |
| Side-port pressure interface (Case 482C) | Enables compact PCB mounting with lateral hose or tube attachment - avoids vertical space constraints. |
| Durable PPS thermoplastic case | Resists moisture, vibration, and thermal cycling - suitable for long-life embedded HVAC and appliance designs. |
| Ratiometric output architecture | Output scales linearly with VS - maintains accuracy even with ±0.25 V supply variation common in unregulated 5 V rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar pressure transducer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV5004GC7U | 0–4 kPa range, 0.2–4.7 V output, same Case 482C package - lower full-scale pressure and identical pinout. | Optimized for ultra-low-pressure applications like gas chromatography column monitoring. | Select when system max pressure is ≤4 kPa and higher sensitivity (1176 mV/kPa) is needed. |
| MPXV7002DP | Dual-port configuration (Case 1351), 0–2 kPa range, 0.2–4.7 V output - different footprint and pressure interface geometry. | Designed for bidirectional differential pressure measurement with symmetric P1/P2 ports. | Choose for true differential (not gauge) sensing where both sides require equal media exposure. |
Compared with MPXV5004GC7U and MPXV7002DP, the MPXV4006GC7U offers the widest usable range (0–6 kPa) among Freescale's SOP gauge sensors with side-port packaging, making it optimal for applications requiring margin above 4 kPa while retaining board-level compatibility with MPXV5004GC7U layouts.

FAQ
What is the pressure port configuration of the MPXV4006GC7U?
The MPXV4006GC7U features a side-port pressure interface per Case 482C-03 mechanical drawing. The pressure (P1) side is identified by the side with the attached port; the vacuum (P2) side is marked by the stainless-steel cap. This orientation allows lateral tubing connection without vertical height penalty - a key advantage over axial-port variants like MPXV4006GC6U.
Does the MPXV4006GC7U require external zeroing circuitry?
No, the MPXV4006GC7U does not require external zeroing components. However, Freescale specifies that "autozeroing" - storing the zero-pressure output value post-installation and subtracting it digitally during operation - is mandatory to achieve the published ±5.0% VFSS accuracy. Mechanical stress from PCB flexure or mounting torque directly affects offset, so system-level software compensation is essential for MPXV4006GC7U.
Can the MPXV4006GC7U be used with media other than dry air?
Freescale qualifies the MPXV4006GC7U exclusively for dry air media. Use with other gases or liquids may degrade long-term reliability and invalidate the ±5.0% VFSS accuracy specification. Media compatibility data for specific fluids (e.g., CO₂, N₂, or medical-grade air) must be requested directly from NXP's legacy Freescale sensor team - no alternate media ratings are published in the MPXV4006GC7U datasheet.
What is the meaning of "N/C" on pins 1, 5–8 of the MPXV4006GC7U?
"N/C" stands for No Connect - these pins are internal device connections with no functional role in external circuitry. Per Freescale documentation, pins 1, 5, 6, 7, and 8 must remain unconnected on the PCB. Soldering or routing to them risks electrical interference, output instability, or permanent damage to the MPXV4006GC7U signal conditioning circuitry.
How does the ratiometric design of the MPXV4006GC7U affect ADC interfacing?
The MPXV4006GC7U output voltage scales linearly with supply voltage (VS), so its transfer function Vout = VS × [(0.1533×P) + 0.045] remains accurate even if VS varies within 4.75–5.25 V. When paired with an MCU ADC using the same VS as its reference voltage, this ratiometric behavior cancels supply drift - meaning MPXV4006GC7U measurements retain precision without requiring a separate voltage reference IC or calibration against supply fluctuations.
