Product details
Overview
MPXHZ6116A6T1 from NXP (formerly Freescale) is an absolute pressure sensor IC with monolithic piezoresistive transducer, on-chip bipolar op amp signal conditioning, and thin-film temperature compensation. It delivers a ratiometric analog output (0.335–4.6 V) over 20–115 kPa, ±1.5% full-scale accuracy from 0 °C to 85 °C, and operates from 4.75–5.25 V supply - used in automotive intake manifold and HVAC pressure monitoring.
For engineers reviewing the MPXHZ6116A6T1 datasheet, MPXHZ6116A6T1 pinout, MPXHZ6116A6T1 application, or MPXHZ6116A6T1 equivalent, key selection criteria include absolute pressure range (20–115 kPa), ratiometric 5 V operation, SSOP-8 package compatibility, and integrated temperature compensation from –40 °C to +125 °C.
Technical Context
The MPXHZ6116A6T1 integrates a silicon piezoresistive sensing element with two-stage gain amplification, thin-film resistor networks for offset and span calibration, and on-die temperature compensation circuitry. Its signal path is fully monolithic, eliminating external trimming components and enabling stable output without external compensation networks.
It features a sealed vacuum reference cavity for absolute pressure measurement, fluorosilicone gel die coat for media resistance, and a thermoplastic (PPS) super small outline package (Case 98ARH99066A). The device is ratiometric: output voltage scales linearly with supply voltage (VOUT = VS × (0.008938 × P − 0.09895)), simplifying A/D interfacing in microcontroller-based systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 20–115 kPa absolute - covers atmospheric variation plus low-pressure boost/vacuum in engine manifolds and cabin air systems. |
| Supply Voltage | 4.75–5.25 V DC - ratiometric operation ensures output scaling with MCU VREF, reducing system-level calibration burden. |
| Full-Scale Span | Typ. 4.2 V at 5 V supply - provides >4 V swing into 12-bit ADC, yielding ~1 kPa resolution without amplification. |
| Offset Voltage | 0.335–0.463 V at min pressure - enables accurate zero-pressure detection and avoids ADC lower-range nonlinearity. |
| Accuracy | ±1.5% VFSS over 0–85 °C - includes linearity, hysteresis, TcSpan, and TcOffset - validated for automotive-grade reliability. |
| Operating Temp | –40 to +125 °C - qualified for under-hood and climate control environments without external thermal management. |
| Sensitivity | Typ. 44.2 mV/kPa - high gain enables direct connection to low-noise ADCs without external instrumentation amplifiers. |
Pinout & Package
MPXHZ6116A6T1 uses an 8-pin Super Small Outline Package (SSOP), Case 98ARH99066A, with gull-wing leads and chamfered corner marking Pin 1. The package is thermoplastic (PPS), media-resistant, and optimized for reflow soldering with recommended footprint per Figure 8 in Rev. 2.1 datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DNC | Do not connect - internal test node; floating or grounded causes calibration drift or damage. |
| 2 | VS | Positive supply input (4.75–5.25 V); requires 100 nF decoupling capacitor per datasheet Figure 4. |
| 3 | GND | Analog ground reference - must be star-connected to ADC ground to minimize noise coupling. |
| 4 | VOUT | Ratiometric analog output (0.335–4.6 V); drives 51 kΩ load minimum; filtered via 47 pF cap per Figure 4. |
| 5–8 | DNC | All unconnected - internal bond wires or test structures; no external connection permitted. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Compensates span and offset across –40 °C to +125 °C using integrated thin-film resistors - eliminates need for external thermistor networks. |
| Media-resistant packaging | Fluorosilicone gel die coat + PPS case withstands humidity, oil mist, and common automotive fluids - validated for intake manifold mounting. |
| Ratiometric output | VOUT scales linearly with VS (e.g., 4.2 V span at 5 V → 4.032 V at 4.8 V) - enables shared VREF with MCU ADC for drift cancellation. |
| High output signal level | Min. 4.2 V full-scale swing at 5 V supply - reduces susceptibility to noise and avoids gain-stage amplification in cost-sensitive designs. |
| Monolithic integration | Sensing element, amplifier, compensation, and calibration all on single die - guarantees matched thermal coefficients and long-term stability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV7002DP | Differential output (0–2 kPa range), dual-port, SO-8 package; lacks on-chip temp compensation beyond 0–85 °C. | Designed for low-differential pressure (e.g., airflow, filter clogging); unsuitable for absolute 20–115 kPa range. | Select MPXV7002DP only when measuring pressure difference across a restriction - not for absolute barometric or manifold pressure. |
| SPX3010-015D | 0–15 psi (0–103 kPa) absolute range, digital I²C output, integrated 12-bit ADC; requires 3.3 V supply and firmware support. | Targets microcontroller-based IoT sensors needing digital interface and auto-calibration; higher system-level integration cost. | Choose SPX3010-015D when digital output, smaller footprint, and built-in diagnostics outweigh analog simplicity and 5 V compatibility. |
Compared with MPXV7002DP and SPX3010-015D, the MPXHZ6116A6T1 offers optimal balance of analog simplicity, automotive-grade temperature range, and calibrated 20–115 kPa absolute coverage - making it preferred for cost-sensitive, high-reliability engine and climate control systems where 5 V ratiometric interfacing is standard.

FAQ
What is the pressure range and output behavior of the MPXHZ6116A6T1?
The MPXHZ6116A6T1 measures absolute pressure from 20 kPa to 115 kPa. Its output is ratiometric: VOUT = VS × (0.008938 × P − 0.09895), delivering 0.335–4.6 V at 5 V supply. This linear, supply-scaled behavior allows direct interfacing with microcontroller ADCs using shared VREF, minimizing calibration drift. The MPXHZ6116A6T1 does not require external amplification or compensation circuits for basic operation.
Is the MPXHZ6116A6T1 suitable for automotive under-hood applications?
Yes, the MPXHZ6116A6T1 is qualified for automotive under-hood use with operating temperature from –40 °C to +125 °C and media resistance provided by fluorosilicone gel die coat and PPS package. It has been validated with air as pressure medium; for non-air media (e.g., oil vapor), consult NXP application engineering. The MPXHZ6116A6T1 meets requirements for intake manifold, turbo boost, and cabin pressure sensing in production vehicles.
What are the power supply requirements for stable operation of the MPXHZ6116A6T1?
The MPXHZ6116A6T1 requires a clean 4.75–5.25 V DC supply with ≤10 mAdc quiescent current. Per datasheet Figure 4, a 100 nF ceramic capacitor must be placed between VS and GND, within 5 mm of the pins. Ripple must be <50 mVpp; excessive noise degrades accuracy. The MPXHZ6116A6T1 draws peak current during internal bias switching, so bulk capacitance is recommended upstream of the 100 nF local cap.
Can unused pins on the MPXHZ6116A6T1 be left floating or tied to ground?
No - Pins 1 and 5–8 are marked DNC (Do Not Connect) and must remain unconnected. Connecting them to ground, supply, or any other node may disrupt internal calibration, cause output errors, or permanently damage the MPXHZ6116A6T1. The datasheet explicitly prohibits external connection to these terminals, as they serve internal test or bond-wire functions only.
How does the MPXHZ6116A6T1 achieve temperature compensation across its full operating range?
The MPXHZ6116A6T1 achieves temperature compensation via on-die thin-film resistor networks that adjust both offset and full-scale span across –40 °C to +125 °C. Compensation is implemented in analog hardware - no software or external components required. The MPXHZ6116A6T1's error band remains within ±1.5% VFSS from 0 °C to 85 °C, and its TcSpan and TcOffset are factory-trimmed and laser-calibrated during wafer sort.
