Product details
Overview
MPXV4115VC6U from NXP Semiconductors (formerly Freescale) is a monolithic silicon differential pressure sensor with on-chip signal conditioning, temperature compensation, and factory calibration. It delivers a ratiometric 0.2–4.6 V analog output over a –115 to 0 kPa vacuum/differential range, operates from 4.75–5.25 V supply, draws ≤10 mA, and achieves ±1.5% full-scale accuracy across 0°C to 85°C - ideal for brake booster and vacuum pump monitoring in automotive systems.
For engineers reviewing the MPXV4115VC6U datasheet, MPXV4115VC6U pinout, MPXV4115VC6U application, or MPXV4115VC6U equivalent, key selection criteria include its differential port configuration (P1/P2), Case 482A-01 thermoplastic SMT package, 1 ms response time, ±0.5%VFSS offset stability after 1000-hour stress testing, and compatibility with microcontroller A/D inputs requiring minimal external circuitry.
Technical Context
The MPXV4115VC6U integrates a piezoresistive sensing element, thin-film temperature compensation network, dual-stage gain amplifier, and ground-reference shift circuitry onto a single die. Its differential mode requires vacuum applied to the metal cap side (P2) and atmospheric pressure on the back side (P1), with fluorosilicone gel isolating the die while transmitting pressure.
It is ratiometric to supply voltage (VS = 5.0 V ± 0.25 V), exhibits 38.26 mV/kPa sensitivity, and uses a decoupling network (1.0 µF + 0.01 µF + 470 pF) to meet electrical specs. Output saturates outside –115 to 0 kPa, and transfer function is defined as Vout = VS × (P × 0.007652 + 0.92) ± error terms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | –115 to 0 kPa differential (vacuum referenced to atmosphere); defines usable sensing span for brake/vacuum monitoring |
| Output Voltage | 0.2 to 4.6 V ratiometric analog output; scales linearly with pressure and supply voltage, simplifying A/D interfacing |
| Accuracy | ±1.5% of full-scale span over 0°C to 85°C; includes linearity, hysteresis, and thermal errors - no additional system calibration needed |
| Response Time | 1.0 ms (10% to 90%); enables real-time detection of rapid vacuum changes in engine control loops |
| Supply Current | 6.0 mA typical, ≤10 mA max at 5 V; supports low-power ECU designs without thermal derating |
| Operating Temp | –40°C to +125°C ambient; qualified for under-hood automotive environments with full functionality at extremes |
| Offset Stability | ±0.5%VFSS after 1000-hour pulsed pressure/temperature cycling; ensures long-term reliability in safety-critical systems |
Pinout & Package
Durable thermoplastic (PPS) surface-mount package, Case 482A-01, 8-pin small outline package with dual ports (P1 and P2). Pins 1, 5, 6, 7, and 8 are No Connects. Port identification: P2 (vacuum) side is the metal cap side; P1 (pressure) side is the port-attached side per datasheet Figure 5 and Pressure/Vacuum Side Identification Table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 2 | VOUT | Analog output signal (0.2–4.6 V); directly interfaces to MCU ADC with minimal filtering |
| Pin 3 | GND | Analog ground reference; must be star-connected to decoupling capacitors to minimize noise |
| Pin 4 | VS | Supply input (4.75–5.25 V); powers internal amplifiers and compensation circuitry |
Key Features
| Feature | Design Value |
|---|---|
| On-chip signal conditioning | Eliminates need for external op-amps or ADC driver stages - reduces BOM count and layout area |
| Factory-calibrated & temperature-compensated | Delivers ±1.5% accuracy over 0–85°C without user calibration - cuts production test time |
| Dual-port differential configuration | Enables true differential vacuum measurement (P1–P2) with isolated media paths - critical for brake booster integrity |
| Ratiometric output | Output scales with supply voltage; rejects common-mode supply ripple when used with same-VS ADC reference |
| Fluorosilicone gel isolation | Protects silicon die from moisture and contaminants while transmitting pressure - extends service life in harsh under-hood conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV5004GC6U | Wider range (–100 to +100 kPa), higher full-scale output (0.2–4.7 V), same Case 482A package and pinout | Supports bidirectional differential pressure (e.g., HVAC airflow reversal), not vacuum-only use cases | Select when system requires symmetric ±100 kPa measurement capability and can accommodate higher output swing |
| SDX100D4 | 0.5% accuracy, digital I²C output, 3.3 V operation, SOIC-8 package with different pin assignment | Requires MCU with I²C interface and firmware support; eliminates analog noise susceptibility but adds protocol overhead | Select when digital interface, tighter accuracy, or lower supply voltage (3.3 V) are prioritized over analog simplicity and 5 V compatibility |
Compared with MPXV4115VC6U, MPXV5004GC6U offers bidirectional range at identical form factor, while SDX100D4 trades analog simplicity for digital precision and lower voltage operation - choice depends on whether analog integration, vacuum-only range, or digital bus compatibility drives the design.

FAQ
What is the correct port orientation for MPXV4115VC6U in differential vacuum sensing?
The MPXV4115VC6U requires vacuum applied to the metal cap side (P2) and atmospheric or reference pressure on the port-attached side (P1). Per the datasheet's Pressure/Vacuum Side Identification Table, the P2 side is identified by the metal cap, and the P1 side is the side with the physical port attached. Incorrect orientation causes inverted or saturated output.
Does MPXV4115VC6U require external calibration for automotive production use?
No, MPXV4115VC6U does not require external calibration. It is factory calibrated and temperature compensated over 0°C to 85°C, delivering ±1.5% full-scale accuracy out-of-box. This eliminates production-line calibration steps and supports zero-defect manufacturing for brake and vacuum systems.
Can MPXV4115VC6U operate reliably at –40°C or +125°C?
MPXV4115VC6U is rated for –40°C to +125°C storage and operating temperature, but its specified accuracy (±1.5% VFSS) applies only from 0°C to 85°C. At –40°C or +125°C, output remains functional and stable, though accuracy degrades per the temperature multiplier curve (factor of 3 at extremes), requiring application-level compensation if high precision is needed.
What decoupling capacitors are required for MPXV4115VC6U to meet datasheet specifications?
MPXV4115VC6U requires the exact decoupling network shown in Figure 3 of the datasheet: 1.0 µF (bulk), 0.01 µF (mid-frequency), and 470 pF (high-frequency) capacitors placed between VS and GND, close to pins 3 and 4. Omitting any capacitor violates the electrical specification and may cause output instability or increased noise in the MPXV4115VC6U output signal.
Is MPXV4115VC6U compatible with 3.3 V microcontrollers?
MPXV4115VC6U is designed for 5.0 V ± 0.25 V supply (4.75–5.25 V) and is not rated for 3.3 V operation. While it may power on at 3.3 V, output voltage drops below 0.2 V at full vacuum, falling outside its guaranteed 0.2–4.6 V range and violating ratiometric behavior. Use only with 5 V systems or add a level-shifting buffer if interfacing to 3.3 V ADCs.
