Product details
Overview
MPXAZ6115AC6T1 from NXP Semiconductors (formerly Freescale) is an absolute pressure sensor IC with integrated signal conditioning, designed for direct interface to microcontroller ADC inputs. It delivers a ratiometric analog output (0.200 V to 4.700 V at 5.0 V supply) across a 15–115 kPa range, features ±1.5% full-scale span accuracy over 0 °C to 85 °C, and operates from -40 °C to +125 °C with on-chip temperature compensation. It is used in engine manifold absolute pressure (MAP) sensing and weather station barometers.
For engineers reviewing the MPXAZ6115AC6T1 datasheet, MPXAZ6115AC6T1 pinout, MPXAZ6115AC6T1 application, or MPXAZ6115AC6T1 equivalent, key selection criteria include its media-resistant fluorosilicone gel encapsulation, 8-pin SOP package (Case 98ASB17757C), 1.0 ms response time, and compatibility with 5 V supply systems requiring stable analog pressure feedback without external amplification.
Technical Context
The MPXAZ6115AC6T1 integrates a piezoresistive silicon diaphragm with bipolar op amp circuitry and thin-film resistor networks to deliver a high-level, temperature-compensated analog voltage output. Its monolithic construction eliminates discrete compensation components and ensures long-term stability under thermal cycling.
It uses a sealed vacuum reference cavity for absolute pressure measurement and relies on fluorosilicone gel to isolate the die from harsh media while transmitting pressure accurately. The transfer function is defined as VOUT = VS × (0.009 × P − 0.095), with error bands specified per temperature and pressure conditions in the official datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 15–115 kPa absolute - covers automotive MAP and atmospheric barometric ranges with margin. |
| Output Voltage Range | 0.200 V to 4.700 V at VS = 5.0 V - directly compatible with 5 V microcontroller ADCs without level-shifting. |
| Accuracy | ±1.5% of full-scale span (VFSS) over 0 °C to 85 °C - enables reliable closed-loop control without calibration per unit. |
| Response Time | 1.0 ms (10% to 90%) - supports dynamic pressure monitoring in fast-transient engine or HVAC applications. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive and industrial environments. |
| Supply Voltage | 4.75–5.25 V DC - ratiometric operation ensures output stability against supply rail variation. |

Pinout & Package
MPXAZ6115AC6T1 is housed in an 8-pin Small Outline Package (SOP), Case 98ASB17757C, with gull-wing leads and chamfered corner marking Pin 1. The package is thermoplastic (PPS), surface-mountable, and qualified for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DNC | Do not connect - no internal connection; must remain floating or unconnected. |
| 2 | VS | Positive supply input (4.75–5.25 V); powers internal amplifier and sensing element. |
| 3 | GND | Analog ground reference; must be low-impedance and tied to system AGND. |
| 4 | VOUT | Analog output (0.200–4.700 V); connects directly to MCU ADC with optional RC filter (e.g., 47 pF + 51 kΩ). |
| 5–8 | DNC | All unconnected - no internal bond wires; must remain unconnected per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Media-resistant gel encapsulation | Fluorosilicone gel isolates die and wire bonds from moisture and automotive fluids while preserving pressure transmission. |
| On-chip temperature compensation | Compensates offset and span errors from -40 °C to +125 °C using integrated circuitry - eliminates need for external compensation. |
| Ratiometric output | Output scales linearly with supply voltage - maintains accuracy even with ±250 mV supply variation. |
| High-level analog output | 4.5 V full-scale span minimizes susceptibility to noise and avoids external amplification in most MCU interfaces. |
| Monolithic silicon construction | Single-die integration of sensing element and signal conditioning improves long-term reliability and reduces assembly cost. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXH6115AC6T1 | Super small outline package (SSOP, Case 98ARH99089A); identical electrical specs but smaller footprint and higher thermal sensitivity. | Better suited for space-constrained PCBs; requires tighter layout control due to smaller pad pitch. | Select when board area is limited and thermal management can accommodate slightly higher TcSpan. |
| MPXA6115AC6T1 | No media-resistant gel; standard plastic package (Case 98ASB17757C); same pinout and electrical behavior. | Lower cost for non-harsh-media applications like lab instrumentation or consumer barometers. | Choose when exposure to automotive fluids or high humidity is not expected - reduces cost without sacrificing core performance. |

FAQ
What is the pressure reference type of the MPXAZ6115AC6T1?
The MPXAZ6115AC6T1 is an absolute pressure sensor with a sealed vacuum reference cavity. It measures pressure relative to perfect vacuum, not ambient or differential pressure. This makes it suitable for barometric and manifold absolute pressure applications where reference stability is critical. The MPXAZ6115AC6T1 achieves this via internal vacuum packaging confirmed in the cross-sectional diagram and transfer function specification.
Does the MPXAZ6115AC6T1 require external calibration or trimming?
No, the MPXAZ6115AC6T1 includes factory-calibrated, on-chip temperature compensation for both offset and full-scale span across -40 °C to +125 °C. Its ±1.5% accuracy over 0 °C to 85 °C is achieved without user calibration. The MPXAZ6115AC6T1 is shipped fully calibrated and ready for direct integration into production systems with no trimming required.
What media is the MPXAZ6115AC6T1 rated for?
The MPXAZ6115AC6T1 uses fluorosilicone gel encapsulation to resist high humidity and common automotive media including engine oil, coolant, and brake fluid. Its qualification is based on dry air testing; for other media, NXP recommends contacting factory support. The MPXAZ6115AC6T1's media resistance is explicitly called out in the datasheet Features section and cross-sectional diagram.
Can the MPXAZ6115AC6T1 operate from a 3.3 V supply?
No - the MPXAZ6115AC6T1 is specified only for 4.75–5.25 V supply. Its ratiometric output and internal amplifier design require 5 V nominal operation. Attempting 3.3 V operation results in undefined output voltage, reduced accuracy, and potential failure to meet datasheet specifications. The MPXAZ6115AC6T1 must be powered from a regulated 5 V rail.
What is the meaning of "DNC" pins on the MPXAZ6115AC6T1?
"DNC" stands for "Do Not Connect." Pins 1 and 5–8 on the MPXAZ6115AC6T1 have no internal connection and must remain unconnected - neither tied to ground nor left floating via pull-up/down. Connecting them risks damaging the device or altering its calibrated performance. This requirement is explicitly stated in Table 1 of the MPXAZ6115AC6T1 datasheet.
