Product details
Overview
MPXV6115VC6U from NXP Semiconductors (formerly Freescale) is a monolithic, signal-conditioned, gauge pressure sensor with piezoresistive sensing element, on-chip temperature compensation, and ratiometric analog output. It measures vacuum pressure from –115 kPa to 0 kPa (gauge), delivers 4.6 V typical full-scale output at 5 V supply, and maintains ±1.5% accuracy across 0–85 °C - used in brake booster and vacuum pump monitoring systems.
For engineers reviewing the MPXV6115VC6U datasheet, MPXV6115VC6U pinout, MPXV6115VC6U application, or MPXV6115VC6U equivalent, key selection criteria include its –115 to 0 kPa gauge range, 1.0 ms response time, 6–10 mA supply current, thermoplastic SOP package (Case 98ASB17757C), and compatibility with microcontroller ADC interfaces requiring ratiometric stability.
Technical Context
The MPXV6115VC6U integrates a silicon micromachined diaphragm with thin-film resistor networks and bipolar op-amp circuitry to generate a high-level analog voltage output proportional to applied vacuum pressure. Its transfer function is VOUT = VS × (0.007652 × P + 0.92), where P is pressure in kPa and VS is supply voltage.
On-chip temperature compensation operates from –40 to +125 °C, with offset stability of ±0.5% VFSS after 1000 pressure/temperature cycles. The device uses fluorosilicone gel isolation and is qualified for dry air media only - not rated for liquid or corrosive media without factory validation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | –115 to 0 kPa gauge; enables precise vacuum measurement down to ~12% of atmospheric pressure. |
| Full-Scale Output | 4.6 V typical at VS = 5.0 V; provides high SNR for 10–12-bit ADC interfacing without external amplification. |
| Accuracy | ±1.5% VFSS over 0–85 °C; includes linearity, temperature hysteresis, pressure hysteresis, and TcSpan/TcOffset errors. |
| Response Time | 1.0 ms (10%–90%); supports real-time vacuum system diagnostics and fast transient detection. |
| Supply Voltage | 4.75–5.25 VDC; ratiometric operation ensures output scaling tracks supply variations, simplifying power design. |
| Operating Temp | –40 to +125 °C; validated for under-hood automotive environments and industrial vacuum control cabinets. |
| Warm-up Time | 20 ms; allows rapid system initialization after power-on without extended stabilization delays. |
Pinout & Package
MPXV6115VC6U is housed in a small outline package (Case 98ASB17757C), through-hole variant with 8-pin configuration and notch-based Pin 1 identification. Package dimensions: 12.70 mm × 10.79 mm × 3.17 mm (L × W × H), lead pitch 2.54 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | DNC | Do not connect; internal test node - floating connection prevents noise coupling or calibration drift. |
| Pin 2 | VS | Positive supply input (4.75–5.25 V); must be decoupled with ≥1 μF ceramic capacitor near package. |
| Pin 3 | GND | Analog ground reference; requires low-impedance return path to minimize offset error in ratiometric output. |
| Pin 4 | VOUT | Ratiometric analog output (0.5–4.6 V); drives ADC inputs directly; load impedance >10 kΩ recommended. |
| Pins 5–8 | DNC | All unconnected internal nodes; no external tie required - PCB layout must isolate these pads from traces. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Validated from –40 to +125 °C; eliminates need for external thermistor networks or software correction tables. |
| High output signal level | 4.6 V full-scale at 5 V supply; reduces susceptibility to noise and enables direct interface with standard SAR ADCs. |
| Fluorosilicone die protection | Hermetically isolates wire bonds and sensing die from ambient moisture while transmitting pressure accurately. |
| Monolithic silicon construction | Single-die integration of piezoresistive element, gain stage, and calibration resistors improves long-term repeatability. |
| Ratiometric output architecture | Output scales linearly with supply voltage; simplifies system-level calibration when using shared LDO or DC-DC rail. |
Applications
| Brake Booster Monitoring | Vacuum Pump Diagnostics |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge vacuum pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV5004GC6U | Wider range (–100 to +100 kPa), lower accuracy (±2.5% VFSS), same SOP-8 package and pinout. | Suitable for bidirectional pressure control (e.g., HVAC damper actuation), not optimized for deep vacuum. | Select when system requires both vacuum and positive pressure measurement in one sensor. |
| SPX3015-015D | Digital I²C output, ±1.0% FS accuracy, 3.3 V supply, smaller DFN-6 package; no internal temp compensation circuitry. | Requires host MCU firmware for temperature correction; better for space-constrained IoT edge nodes with digital buses. | Select when board space is limited and system already implements digital calibration routines. |
Compared with MPXV6115VC6U, MPXV5004GC6U offers bidirectional capability at reduced vacuum accuracy, while SPX3015-015D trades analog simplicity for digital integration and tighter size - neither is pin-compatible, but both serve overlapping vacuum-sensing use cases with distinct trade-offs in accuracy, interface, and form factor.

FAQ
What is the pressure media compatibility of the MPXV6115VC6U?
The MPXV6115VC6U is qualified for use with dry air only. Its fluorosilicone gel isolation and silicon diaphragm are not rated for liquids, oils, or corrosive gases without prior factory validation. Exposure to incompatible media may cause irreversible drift or failure. Always consult NXP's media compatibility documentation before deploying MPXV6115VC6U in non-air environments.
Does the MPXV6115VC6U require external calibration components?
No, the MPXV6115VC6U does not require external calibration components. It features fully integrated on-chip temperature compensation and factory-trimmed thin-film resistor networks that deliver ±1.5% VFSS accuracy from 0 to 85 °C without user adjustment. External decoupling capacitors (1 μF on VS, 100 nF on VOUT) are required for noise suppression but not calibration.
What is the meaning of "DNC" on pins 1 and 5–8 of the MPXV6115VC6U?
"DNC" stands for "Do Not Connect." Pins 1 and 5–8 are internal test or unused nodes tied to internal circuitry during wafer probe or calibration. Connecting them to ground, supply, or signals will disrupt sensor operation, induce offset errors, or damage the die. PCB layout must leave these pads unconnected and isolated from all routing layers.
Can the MPXV6115VC6U operate with a 3.3 V supply?
No, the MPXV6115VC6U is specified only for 4.75–5.25 VDC supply. Operation below 4.75 V violates maximum ratings and causes output saturation, increased error, or failure to meet datasheet accuracy. For 3.3 V systems, use NXP's MP3V5050 or Infineon's DPS310 - both offer compatible vacuum ranges and 3.3 V operation.
How does the ratiometric output of the MPXV6115VC6U benefit system design?
The MPXV6115VC6U's ratiometric output means VOUT scales linearly with VS - e.g., if VS drops to 4.9 V, full-scale output proportionally decreases to ~4.51 V. This allows the same ADC reference voltage to be used for both supply monitoring and sensor reading, eliminating ratio-metric error sources and simplifying calibration in systems with shared LDO rails or variable input voltages.
