Product details
Overview
MPXV4115V6T1 from Freescale Semiconductor is a monolithic silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and factory calibration. It delivers a ratiometric analog output (0.2–4.6 V) over a –115 to 0 kPa vacuum/gauge range, operates at 5.0 V ±0.25 V supply, draws ≤10 mA, and achieves ±1.5% full-scale accuracy across 0°C to 85°C - used in brake booster and vacuum pump monitoring systems.
For engineers reviewing the MPXV4115V6T1 datasheet, MPXV4115V6T1 pinout, MPXV4115V6T1 application, or MPXV4115V6T1 equivalent, this page provides verified package mapping, validated terminal roles, confirmed transfer function coefficients, thermal error band data, and real-world interface guidance for microcontroller A/D integration.
Technical Context
The MPXV4115V6T1 integrates a shear-stress strain gauge, thin-film metallization, and bipolar signal conditioning circuitry onto a single die. Its output is ratiometric to supply voltage (VS = 4.75–5.25 V), with gain and offset trimmed during calibration to deliver stable performance across –40°C to +125°C operating temperature.
It uses differential sensing with vacuum applied to the metal cap side (P2) and atmospheric pressure on the back side (P1), requiring dry air as the pressure medium. The internal architecture includes two gain stages, ground reference shift circuitry, and fluorosilicone gel isolation of the die surface and wire bonds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | –115 to 0 kPa vacuum/gauge; defines usable differential input where output remains linear and saturated only outside bounds |
| Output Voltage Range | 0.2 to 4.6 V at VS = 5.0 V; enables direct connection to 5 V microcontroller A/D inputs without level-shifting |
| Supply Voltage | 4.75–5.25 Vdc; ratiometric operation ensures output scaling tracks supply variations, simplifying system-level calibration |
| Accuracy | ±1.5% of full-scale span at 0–85°C; includes linearity, temperature hysteresis, pressure hysteresis, TcSpan, and TcOffset errors |
| Sensitivity | 38.26 mV/kPa nominal; determines resolution per pressure step - e.g., ~0.26 kPa per LSB for 12-bit 5 V A/D |
| Response Time | 1.0 ms (10%–90%); supports real-time vacuum monitoring in dynamic braking or pump control loops |
| Operating Temperature | –40°C to +125°C; qualified for under-hood automotive environments with full functionality down to cold start |
Pinout & Package
Durable thermoplastic (PPS) small-outline package, Case 482-01, surface-mountable with 8-pin footprint. Pins 1, 5, 6, 7, and 8 are No Connects; functional terminals are VS (Pin 2), VOUT (Pin 3), and GND (Pin 4).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 2 (VS) | Supply Input | 5.0 V ±0.25 V excitation source; powers internal amplifier chain and sets ratiometric output scale |
| Pin 3 (VOUT) | Analog Output | High-impedance buffered voltage proportional to applied vacuum; requires external decoupling (0.01 µF + 470 pF) |
| Pin 4 (GND) | Ground Reference | Return path for supply current and output stage; must be low-impedance to minimize offset drift |
| Pins 1,5,6,7,8 | No Connect | Internally unconnected; must remain floating - no PCB traces or solder mask openings required |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar pressure transducer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV5115V | Wider pressure range (–115 to +115 kPa), higher full-scale output (0.2–4.8 V), same package and pinout | Supports bidirectional differential pressure; unsuitable for pure vacuum-only use cases due to extended positive range | Select MPXV5115V only if bidirectional sensing is required; MPXV4115V6T1 remains optimal for dedicated vacuum/gauge measurement. |
| MPXH6115A | Higher accuracy (±1.0% VFSS), wider operating temp (–40°C to +150°C), but requires external compensation and lacks ratiometric output | Demands additional op-amp circuitry and calibration effort; not drop-in compatible with MPXV4115V6T1's self-contained architecture | Choose MPXH6115A only when extreme accuracy or extended high-temp operation justifies added design complexity and cost. |
Compared with MPXV5115V and MPXH6115A, the MPXV4115V6T1 offers the lowest system-level integration burden for vacuum-specific applications - delivering calibrated, temperature-compensated, ratiometric output from a single 8-pin SOP without external components or firmware compensation.

FAQ
What is the pressure media compatibility of the MPXV4115V6T1?
The MPXV4115V6T1 is qualified for use with dry air as the pressure medium. Other media may degrade long-term reliability or alter output characteristics. Freescale's internal qualification testing was performed exclusively with dry air; media tolerance data for alternate fluids or gases must be requested directly from NXP (formerly Freescale) for validation prior to deployment. The MPXV4115V6T1 incorporates fluorosilicone gel isolation, which provides environmental protection but does not guarantee chemical compatibility beyond dry air.
Does the MPXV4115V6T1 require external decoupling capacitors?
Yes - the MPXV4115V6T1 requires a minimum decoupling network: 1.0 µF bulk capacitor, 0.01 µF ceramic capacitor, and 470 pF filter capacitor between VS and GND, as specified in Figure 3 of the official datasheet. Omitting these components risks violating electrical specifications including noise immunity, response time, and output stability. The MPXV4115V6T1's internal circuitry assumes this filtering is present to meet its published 1.0 ms response time and ±1.5% accuracy.
What is the meaning of "ratiometric" in the MPXV4115V6T1 specification?
"Ratiometric" means the MPXV4115V6T1's output voltage scales linearly with its supply voltage (VS). For example, if VS drops from 5.0 V to 4.9 V, the full-scale output decreases proportionally - preserving measurement ratio integrity. This allows the MPXV4115V6T1 to interface directly with microcontroller ADCs using the same VS as the ADC reference, eliminating need for separate precision voltage references. The MPXV4115V6T1 maintains this behavior across its 4.75–5.25 V supply range.
How is the MPXV4115V6T1 calibrated during manufacturing?
The MPXV4115V6T1 undergoes factory calibration at multiple pressure points (0 kPa and –115 kPa) and temperatures (0°C, 25°C, 85°C) to trim internal gain and offset circuitry. This process corrects for inherent piezoresistive element nonlinearity, temperature-induced span and offset drift, and process variation - resulting in ±1.5% full-scale accuracy without requiring end-user calibration. The MPXV4115V6T1's calibration data is permanently stored in on-die circuitry and cannot be reprogrammed.
Can the MPXV4115V6T1 be used in differential pressure mode with both ports active?
No - the MPXV4115V6T1 is configured exclusively for vacuum/gauge operation: vacuum applied to the metal cap side (P2), atmospheric pressure on the back side (P1). Its internal transfer function and calibration assume this fixed differential orientation. While physically symmetrical, the MPXV4115V6T1 lacks dual-port sealing or independent port referencing; attempting reverse or bidirectional differential use invalidates accuracy specs and may cause irreversible offset shift. Use MPXV5115V for true differential applications.
