Product details
Overview
MPXAZ6115AC6U from Freescale Semiconductor is a monolithic, signal-conditioned, absolute pressure sensor with 15–115 kPa range, ±1.5% full-scale accuracy over 0 °C to 85 °C, and ratiometric 0.2 V to 4.7 V analog output at 5.0 V supply - designed for engine manifold absolute pressure (MAP) sensing in automotive control systems.
For engineers reviewing the MPXAZ6115AC6U datasheet, MPXAZ6115AC6U pinout, MPXAZ6115AC6U application, or MPXAZ6115AC6U equivalent, key selection criteria include its media-resistant fluorosilicone gel encapsulation, -40 °C to +125 °C operating temperature range, 1.0 ms response time, and compatibility with microcontroller ADC interfaces requiring stable ratiometric scaling.
Technical Context
The MPXAZ6115AC6U integrates piezoresistive silicon diaphragm sensing with on-chip bipolar op amp circuitry and thin-film resistor networks for temperature compensation and signal conditioning. It delivers a calibrated, linear analog voltage output proportional to absolute pressure referenced to sealed vacuum.
Its architecture includes internal offset and span calibration across temperature, with TcOffset and TcSpan compensation active from -40 °C to +125 °C. The device operates ratiometrically: output scales directly with supply voltage (4.75–5.25 V), enabling robust performance in noisy automotive power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 15–115 kPa absolute - matches typical intake manifold vacuum-to-boost range in naturally aspirated and turbocharged gasoline engines. |
| Accuracy | ±1.5% of full-scale span (VFSS) over 0 °C to 85 °C - ensures reliable air mass calculation without external calibration in ECU applications. |
| Output Voltage | 0.133–4.768 V at VS = 5.0 V - provides >4.5 V full-scale span for high-resolution ADC digitization with noise margin. |
| Response Time | 1.0 ms (10% to 90%) - supports real-time transient pressure tracking during rapid throttle transients. |
| Operating Temp | -40 °C to +125 °C - qualified for under-hood placement with no derating required in passenger vehicle environments. |
| Supply Voltage | 4.75–5.25 V DC - ratiometric operation eliminates need for precision voltage reference in ECU designs. |
| Media Resistance | Fluorosilicone gel isolation - enables direct exposure to humid air, fuel vapors, and common automotive fluids without drift. |
Pinout & Package
MPXAZ6115AC6U uses the small outline package Case 98ASB17757C (8-pin SOP), with pin 1 identified by chamfered corner. Pins 5–8 are DNC (do not connect); only pins 1 (DNC), 2 (VS), 3 (GND), and 4 (VOUT) are functional.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | DNC | Do not connect - mechanical pin 1 identifier only; electrically isolated per datasheet. |
| Pin 2 | VS | 5.0 V supply input - powers internal amplifier and sensor bridge; ratiometric reference for output scaling. |
| Pin 3 | GND | Analog ground return - must be low-impedance path shared with ADC reference ground to minimize offset error. |
| Pin 4 | VOUT | Analog output - 0.2–4.7 V ratiometric voltage proportional to absolute pressure; drives 100 nF/51 kΩ RC filter per typical application. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Calibrated offset and span over -40 °C to +125 °C - eliminates need for external thermistor or software compensation in MAP sensors. |
| Media-resistant encapsulation | Fluorosilicone gel isolates die and wire bonds - maintains long-term stability when exposed to humidity, oil mist, and fuel vapor in engine bays. |
| Ratiometric output | Output scales linearly with VS (4.75–5.25 V) - allows use of same ECU supply rail for sensor and ADC reference, reducing BOM count. |
| High reliability packaging | Durable thermoplastic (PPS) case with 8-pin SOP footprint - compatible with standard SMT reflow and qualified for automotive vibration/shock requirements. |
| Fast dynamic response | 1.0 ms rise time - captures rapid pressure changes during transient engine operation (e.g., tip-in/tip-out). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXH6115AC6U | Super small outline package (Case 98ARH99089A), identical electrical specs but 30% smaller footprint. | Preferred where PCB space is constrained (e.g., compact ECU modules); same media resistance and temperature range. | Select MPXH6115AC6U when board area is limited and rework tolerance for fine-pitch SSOP is acceptable. |
| MPXAZ6115AP | Tray-packaged version in Case 98ASA99303D; same die and calibration, different leadframe geometry and moisture sensitivity level. | Used in high-volume automated assembly with tray feeders; slightly higher thermal resistance due to package variant. | Choose MPXAZ6115AP for high-throughput SMT lines using tray delivery and where JEDEC MSL-3 handling is established. |
Compared with MPXAZ6115AC6U, MPXH6115AC6U offers identical performance in a smaller SSOP package ideal for space-constrained designs, while MPXAZ6115AP provides tray-based manufacturability with matched calibration - neither is pin-compatible, but all three share the same transfer function and application circuitry.

FAQ
What is the pressure range and output behavior of the MPXAZ6115AC6U?
The MPXAZ6115AC6U measures absolute pressure from 15 kPa to 115 kPa with a ratiometric analog output ranging from approximately 0.133 V to 4.768 V at 5.0 V supply. Its transfer function is defined as VOUT = VS × (0.009 × P − 0.095), where P is pressure in kPa. This linear relationship enables straightforward air mass calculation in engine control applications without complex lookup tables.
Is the MPXAZ6115AC6U pin-compatible with other devices in the MPXxx6115A family?
No - the MPXAZ6115AC6U uses Case 98ASB17757C (8-pin SOP), while MPXH6115AC6U uses Case 98ARH99089A (SSOP) and MPXAZ6115AP uses Case 98ASA99303D (SOP variant). Though all share identical pin functions (VS, GND, VOUT, DNC), their physical footprints, dimensions, and solder pad layouts differ. PCB layout must be redesigned for each package type.
Does the MPXAZ6115AC6U require external temperature compensation?
No - the MPXAZ6115AC6U features fully integrated on-chip temperature compensation covering -40 °C to +125 °C. Its offset and full-scale output are factory-calibrated across temperature, eliminating the need for external thermistors, digital compensation algorithms, or calibration coefficients in most applications.
What media is the MPXAZ6115AC6U rated for, and how does its gel encapsulation work?
The MPXAZ6115AC6U uses fluorosilicone gel to isolate the silicon die and wire bonds from environmental exposure while transmitting pressure mechanically to the diaphragm. It is resistant to humid air, fuel vapors, and common automotive fluids - but not recommended for direct contact with aggressive solvents or corrosive gases. Media compatibility testing is advised for non-standard applications.
Can the MPXAZ6115AC6U operate from a 3.3 V supply?
No - the MPXAZ6115AC6U is specified only for 4.75–5.25 V supply. At 3.3 V, output voltage falls below minimum operational threshold, causing saturation and loss of linearity. For 3.3 V systems, consider NXP's newer KMA210 or MP3V5050 series, which are explicitly rated for lower supply rails.
