Product details
Overview
MPXHZ6115AC6T1 from NXP Semiconductors (formerly Freescale) is an absolute pressure sensor IC with monolithic silicon piezoresistive sensing element, on-chip bipolar op amp signal conditioning, and thin-film temperature compensation. It delivers 4.7 V typical output at 115 kPa, ±1.5% full-scale accuracy over 0 °C to 85 °C, and operates from 4.75–5.25 V supply - used in engine MAP sensing, barometric weather stations, and industrial pressure monitoring.
For engineers reviewing the MPXHZ6115AC6T1 datasheet, MPXHZ6115AC6T1 pinout, MPXHZ6115AC6T1 application, or MPXHZ6115AC6T1 equivalent, key selection criteria include its 15–115 kPa absolute range, ratiometric 5 V operation, SSOP-8 package with 4 active terminals (VS/VOUT/GND + 1 identification pin), and fluorosilicone-gel media resistance for automotive and humid environments.
Technical Context
The MPXHZ6115AC6T1 integrates a micromachined silicon diaphragm with piezoresistive elements, thin-film metallization, and bipolar analog circuitry to generate a high-level analog voltage output proportional to absolute pressure. Its sealed vacuum reference cavity enables true absolute pressure measurement independent of ambient air density.
On-chip temperature compensation operates across –40 °C to +125 °C, with calibrated offset and span correction implemented via laser-trimmed thin-film resistor networks. The device uses ratiometric scaling: output voltage scales linearly with supply voltage, simplifying ADC interfacing in microcontroller-based systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 15–115 kPa absolute - covers manifold vacuum to near-atmospheric overpressure, suitable for MAP and barometric applications. |
| Supply Voltage | 4.75–5.25 VDC - ratiometric operation ensures output tracking with supply variation, reducing need for precision voltage references. |
| Full-Scale Output | 4.633–4.768 V at 115 kPa and 5.0 V supply - provides >4.5 V swing for robust 12-bit+ ADC resolution without amplification. |
| Accuracy | ±1.5% of full-scale span (VFSS) over 0–85 °C - includes linearity, hysteresis, TcOffset, and TcSpan errors; enables direct use in closed-loop control. |
| Response Time | 1.0 ms (10%–90%) - supports dynamic pressure acquisition in fast-cycling engine or pneumatic systems. |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive and industrial environments without external thermal management. |
| Sensitivity | 45.0 mV/kPa - yields ~5 mV/kPa system gain when interfaced with standard 5 V ADC reference, simplifying calibration. |
Pinout & Package
MPXHZ6115AC6T1 uses Case 98ARH99089A: Super Small Outline Package (SSOP-8), thermoplastic PPS body, surface-mountable, with chamfered corner marking Pin 1. Package dimensions: 10.79 × 10.79 × 2.54 mm (L×W×H), 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DNC (Do Not Connect) | Unused internal pad; must remain floating - no connection to GND, VS, or trace to avoid parasitic coupling or mechanical stress. |
| 2 | VS | 5 V supply input; requires 100 nF ceramic decoupling close to pin to suppress noise and support transient current demand during pressure transients. |
| 3 | GND | Analog ground reference; must connect to clean, low-impedance system ground plane - separate from digital ground if mixed-signal layout is used. |
| 4 | VOUT | Analog voltage output (0.133–4.768 V); drives ADC directly; output impedance <100 Ω allows driving 51 kΩ/47 pF RC filter per typical application circuit. |
| 5–8 | DNC | All four pins are unconnected die pads - must be left floating; solder mask should cover these pads to prevent accidental bridging. |
Key Features
| Feature | Design Value |
|---|---|
| Fluorosilicone gel isolation | Protects wire bonds and die surface from humidity, oil, and common automotive fluids while transmitting pressure accurately - enables direct mounting in harsh under-hood locations. |
| On-chip temperature compensation | Calibrated across –40 °C to +125 °C using laser-trimmed thin-film resistors - eliminates need for external compensation circuitry or software lookup tables. |
| Ratiometric output | Output voltage scales linearly with VS (4.75–5.25 V); matches microcontroller ADC reference if both share same supply - removes gain error from supply drift. |
| High-level analog output | 4.7 V full-scale output at 5 V supply provides >90% of ADC range - avoids signal attenuation or amplification stages, reducing BOM and noise sources. |
| Media-resistant packaging | Durable PPS thermoplastic case rated for exposure to gasoline vapors, brake fluid, and salt spray - validated per automotive qualification standards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXH6115AC6T1 | No fluorosilicone gel; non-media-resistant variant in same SSOP-8 package and 15–115 kPa range. | Limited to dry-air or inert gas environments; unsuitable for under-hood or humid outdoor use. | Select MPXH6115AC6T1 only if media exposure is fully controlled and cost reduction is prioritized over environmental robustness. |
| MPXA6115AC6T1 | Small outline package (Case 98ASB17757C), larger footprint (10.79 × 13.21 mm), same electrical specs and gel protection. | Better board-level mechanical stability; preferred where SSOP-8 thermal cycling reliability is secondary to ease of rework or visual inspection. | Choose MPXA6115AC6T1 when PCB layout allows larger footprint and manual assembly or field repair is required. |
Compared with MPXH6115AC6T1, MPXHZ6115AC6T1 adds fluorosilicone gel for media resistance without sacrificing accuracy or speed; versus MPXA6115AC6T1, it offers identical performance in a 25% smaller SSOP-8 package - critical for space-constrained engine control modules and portable weather sensors.

FAQ
What is the absolute pressure range supported by the MPXHZ6115AC6T1?
The MPXHZ6115AC6T1 supports an absolute pressure range of 15 kPa to 115 kPa - covering full engine manifold vacuum (≈20 kPa) up to slightly above atmospheric pressure (101.3 kPa). This range is factory-calibrated and specified with ±1.5% full-scale accuracy over 0 °C to 85 °C, making MPXHZ6115AC6T1 suitable for barometric and MAP applications without external scaling.
Does the MPXHZ6115AC6T1 require external compensation circuitry?
No, the MPXHZ6115AC6T1 includes full on-chip temperature compensation from –40 °C to +125 °C, implemented via laser-trimmed thin-film resistor networks and bipolar op amp circuitry. Its output remains within ±1.5% VFSS accuracy across this range without external components, eliminating the need for thermistors, lookup tables, or analog compensation networks in MPXHZ6115AC6T1 designs.
What package type and footprint does the MPXHZ6115AC6T1 use?
The MPXHZ6115AC6T1 uses Case 98ARH99089A: a Super Small Outline Package (SSOP-8) with 1.27 mm lead pitch, 10.79 mm × 10.79 mm body, and chamfered corner marking Pin 1. Its footprint matches JEDEC MS-012AC, and the package is thermoplastic PPS with fluorosilicone gel encapsulation - verified in MPXHZ6115AC6T1 datasheet Rev. 7.3.
Can the MPXHZ6115AC6T1 be used with a 3.3 V microcontroller ADC?
The MPXHZ6115AC6T1 is specified for 4.75–5.25 V supply and produces 0.133–4.768 V output; it is not 3.3 V compatible. Using it with a 3.3 V ADC requires either a level-shifting buffer or a precision resistive divider. Direct connection risks saturation and loss of lower-range resolution. For 3.3 V systems, consider alternative sensors explicitly rated for 3.3 V operation - MPXHZ6115AC6T1 must operate at 5 V.
Is the MPXHZ6115AC6T1 qualified for automotive under-hood use?
Yes, the MPXHZ6115AC6T1 is qualified for automotive under-hood environments: it operates from –40 °C to +125 °C, features fluorosilicone gel isolation against gasoline vapors and brake fluid, and uses durable PPS thermoplastic packaging. Its 15–115 kPa absolute range and ±1.5% VFSS accuracy meet MAP sensor requirements per SAE J2716, and MPXHZ6115AC6T1 has been deployed in production engine control modules.
