Product details
Overview
MPXH6115AC6U from Freescale Semiconductor is a monolithic, signal-conditioned, absolute pressure sensor with 15–115 kPa range, ratiometric 5 V supply operation, ±1.5% full-scale accuracy over 0 °C to 85 °C, and integrated temperature compensation from –40 °C to +125 °C. It delivers a high-level analog output (0.200–4.700 V) for engine manifold absolute pressure (MAP) sensing in automotive control systems.
For engineers reviewing the MPXH6115AC6U datasheet, MPXH6115AC6U pinout, MPXH6115AC6U application, or MPXH6115AC6U equivalent, this page provides verified technical context, validated pin functions, real-world use cases in MAP and barometric sensing, and confirmed alternative parts with documented functional differences.
Technical Context
The MPXH6115AC6U integrates a piezoresistive silicon diaphragm with on-chip bipolar op amp circuitry and thin-film resistor networks to deliver a calibrated, temperature-compensated analog voltage output proportional to absolute pressure. Its sealed vacuum reference enables true absolute pressure measurement without external calibration.
It operates ratiometrically with a 4.75–5.25 V supply, draws 6–10 mA, and features a 1 ms response time with 20 ms warm-up time. The fluorosilicone gel die coat isolates the sensing element while transmitting pressure, supporting reliable operation in humid and automotive media environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 15–115 kPa absolute - defines usable operating window for MAP and barometric applications without saturation. |
| Supply Voltage | 4.75–5.25 Vdc - ratiometric operation ensures output scaling remains stable across supply variation. |
| Output Voltage Range | 0.133–4.768 Vdc - spans >4.6 V full-scale span, enabling high-resolution ADC digitization with minimal gain. |
| Accuracy | ±1.5 %VFSS over 0 °C to 85 °C - includes linearity, hysteresis, and thermal errors; supports closed-loop engine control. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive environments with on-chip TcOffset and TcSpan compensation. |
| Response Time | 1.0 ms (10%–90%) - fast enough to track dynamic intake manifold pressure transients during throttle transitions. |
| Warm-up Time | 20 ms - ensures stable output within two engine control loop cycles after power-on. |
Pinout & Package
MPXH6115AC6U uses the super small outline package (Case 98ARH99089A), an 8-pin surface-mount thermoplastic (PPS) housing with chamfered corner pin 1 identification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DNC | Do not connect - electrically isolated; used only for mechanical alignment and pin 1 marking. |
| 2 | VS | Voltage supply input - accepts 4.75–5.25 Vdc; powers internal amplifier and sensing bridge. |
| 3 | GND | Analog ground reference - must be low-impedance return path shared with ADC and supply decoupling. |
| 4 | VOUT | Analog output - ratiometric voltage (0.133–4.768 V) directly interfaced to 10-bit+ ADC without external amplification. |
| 5–8 | DNC | Do not connect - no internal connection; must remain floating per datasheet specification. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Compensates offset and span across –40 °C to +125 °C using integrated circuitry-eliminates need for external calibration or software correction. |
| Fluorosilicone gel isolation | Protects wire bonds and die from humidity and automotive fluids while preserving pressure transmission-enables long-term reliability in harsh environments. |
| Ratiometric output | Output scales linearly with supply voltage-allows direct interface to microcontroller ADCs referenced to same VS, rejecting supply noise. |
| High-level analog output | 4.5 V full-scale span at 5 V supply-reduces susceptibility to noise and eliminates need for external gain stages in most embedded designs. |
| Sealed vacuum reference | Enables true absolute pressure measurement without external reference port-simplifies mechanical integration in MAP and barometer modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXH6115A6U | Same die and compensation, but shipped in rails with Case 98ARH99066A package (vs. 98ARH99089A); identical electrical specs. | No functional difference-only packaging and reel vs. rail delivery format; both rated for same pressure/temperature ranges. | Select MPXH6115A6U only if board layout accommodates Case 98ARH99066A footprint and volume procurement requires tape-and-reel alternatives. |
| MPXHZ6115AC6U | Media-resistant gel variant-adds fluorosilicone encapsulation optimized for aggressive fluids (e.g., brake fluid, coolant); otherwise identical pinout and transfer function. | Better suited for direct exposure to automotive liquids; MPXH6115AC6U is rated for humid air and standard engine bay environments only. | Choose MPXHZ6115AC6U when sensor mounting location risks contact with non-dry-air media; MPXH6115AC6U suffices for sealed MAP ports and barometers. |
Compared with MPXH6115AC6U, MPXH6115A6U offers identical performance in a different package variant for alternate assembly logistics, while MPXHZ6115AC6U adds enhanced media resistance at no cost to accuracy or speed-making it the preferred choice where fluid exposure is unavoidable.

FAQ
What is the absolute pressure range supported by the MPXH6115AC6U?
The MPXH6115AC6U supports an absolute pressure range of 15 kPa to 115 kPa. This range is defined with respect to a sealed vacuum reference and is validated for linear output and specified accuracy across the full span. Operation outside this range may cause saturation or increased error beyond ±1.5% VFSS, and the device is rated for a maximum pressure of 400 kPa without damage.
Does the MPXH6115AC6U require external calibration or trimming?
No, the MPXH6115AC6U does not require external calibration or trimming. It integrates on-chip temperature compensation and factory calibration for offset, span, and thermal coefficients across –40 °C to +125 °C. The output voltage is fully characterized and guaranteed per datasheet specifications (e.g., 0.200 V typical offset and 4.700 V typical full-scale output at 5.0 V supply and 25 °C), eliminating need for user calibration.
What is the supply current consumption of the MPXH6115AC6U?
The MPXH6115AC6U draws 6.0 mA typical and up to 10 mA maximum supply current at 5.0 Vdc and 25 °C. Current remains stable across temperature and pressure, with no significant load-dependent variation. This low quiescent current supports integration into power-sensitive automotive and portable systems without requiring additional regulation or heat sinking.
Can the MPXH6115AC6U be used in differential or gauge pressure configurations?
No, the MPXH6115AC6U is strictly an absolute pressure sensor with a sealed vacuum reference cavity. It cannot be configured for differential or gauge measurements. Its internal architecture lacks a second pressure port or vent path; attempting to expose the backside or modify the package voids specifications and risks permanent damage. For differential or gauge applications, select MPXV7002DP or MPX2010 series instead.
What package type and footprint does the MPXH6115AC6U use?
The MPXH6115AC6U uses the super small outline package Case 98ARH99089A-an 8-pin thermoplastic (PPS) surface-mount housing with 2.54 mm lead pitch. Its recommended PCB footprint matches the SSOP pattern in Figure 10 of the MPXA6115A datasheet Rev. 7.3, including 0.69 mm pad width and 9.83 mm body length. Pin 1 is identified by a chamfered corner.
