Product details
Overview
MPXHZ6115A6U from NXP (formerly Freescale) is a monolithic, signal-conditioned absolute pressure sensor with integrated bipolar op amp and thin-film resistor networks. It delivers a ratiometric analog output (0.200 V to 4.700 V at 5.0 V supply) over a 15–115 kPa range, ±1.5% full-scale span accuracy from 0 °C to 85 °C, and operates across –40 °C to +125 °C. It is used in engine manifold absolute pressure (MAP) sensing and barometric measurement.
For engineers reviewing the MPXHZ6115A6U datasheet, MPXHZ6115A6U pinout, MPXHZ6115A6U application, or MPXHZ6115A6U equivalent, key selection considerations include its super small outline package (Case 98ARH99066A), 1.0 ms response time, fluorosilicone gel media isolation, on-chip temperature compensation, and compatibility with microcontroller ADC interfaces requiring stable 5 V excitation.
Technical Context
The MPXHZ6115A6U integrates a piezoresistive silicon diaphragm with on-die signal conditioning, including bipolar amplifier circuitry and thin-film resistor networks for offset and span calibration. Its sealed vacuum reference enables absolute pressure measurement with no external reference port.
It features ratiometric operation (output scales linearly with supply voltage between 4.75 V and 5.25 V), internal temperature compensation from –40 °C to +125 °C, and fluorosilicone gel encapsulation for resistance to automotive fluids and high humidity. Output is a single-ended voltage referenced to GND, with 45 mV/kPa sensitivity and 4.5 V full-scale span.
Key Specifications

Pinout & Package
MPXHZ6115A6U uses a thermoplastic (PPS) super small outline package (Case 98ARH99066A), 8-pin surface-mount with chamfered corner marking Pin 1. The package is media-resistant due to fluorosilicone gel die coating and sealed vacuum reference cavity.

| 2 | VS | Positive supply input (4.75–5.25 Vdc); powers internal op amp and sensor bridge. |
| 3 | GND | Analog ground reference; must be low-impedance return path for supply and output. |
| 4 | VOUT | Analog voltage output (0.200–4.700 Vdc); connects directly to MCU ADC input with 100 nF bypass. |
| 5–8 | DNC | All unconnected; no internal bond wires or circuitry; must remain floating per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Calibrated across –40 °C to +125 °C; eliminates need for external compensation circuitry or software lookup tables. |
| Fluorosilicone gel isolation | Protects die and wire bonds from automotive fluids, moisture, and particulates while transmitting pressure accurately. |
| Ratiometric output | Output scales linearly with VS; allows shared 5 V regulator for sensor and ADC, reducing system error sources. |

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 | No fluorosilicone gel; standard SSOP package (same Case 98ARH99066A) but rated for dry air only. | Limited to clean, non-corrosive media; unsuitable for direct exposure to oil, coolant, or high-humidity condensing environments. | Select MPXH6115A6U only when media compatibility is not required and cost optimization is prioritized. |
| MPXA6115A6U | Small outline package (Case 98ASB17756C); larger footprint (12.7 × 10.79 mm), same electrical specs and gel isolation. | Better suited for manual assembly or legacy PCB layouts; less space-constrained than SSOP variants. | Choose MPXA6115A6U when board real estate permits and reflow compatibility with SOP footprints is preferred. |
Compared with MPXHZ6115A6U, MPXH6115A6U lacks media-resistant gel and requires cleaner operating environments, while MPXA6115A6U offers identical performance in a larger SOP package-making MPXHZ6115A6U optimal for space-constrained, harsh-media automotive and industrial designs.

FAQ
What is the pressure range and output behavior of the MPXHZ6115A6U?
The MPXHZ6115A6U measures absolute pressure from 15 kPa to 115 kPa with a ratiometric analog output ranging from 0.200 V to 4.700 V at 5.0 V supply. Its transfer function is VOUT = VS × (0.009 × P − 0.095), where P is pressure in kPa. This linear relationship simplifies calibration and enables direct ADC interfacing without external amplification in most microcontroller-based systems using the MPXHZ6115A6U.
Does the MPXHZ6115A6U require external compensation or calibration?
No, the MPXHZ6115A6U includes on-chip temperature compensation and factory calibration across –40 °C to +125 °C. It delivers specified accuracy (±1.5% VFSS) over 0 °C to 85 °C without external circuitry or software compensation. The MPXHZ6115A6U's integrated bipolar op amp and thin-film resistor network handle offset, span, and thermal drift internally-reducing system-level design effort and BOM count.
What media is the MPXHZ6115A6U qualified for, and how is it protected?
The MPXHZ6115A6U is qualified for exposure to high humidity and common automotive media (e.g., engine oil, coolant, brake fluid) due to its fluorosilicone gel die coating and sealed vacuum reference cavity. This gel isolates the silicon die and wire bonds while transmitting pressure accurately. The MPXHZ6115A6U's PPS thermoplastic package further enhances chemical resistance-making it suitable for under-hood and outdoor deployments where condensation or fluid splash may occur.
What is the recommended supply configuration for the MPXHZ6115A6U?
The MPXHZ6115A6U requires a stable 4.75–5.25 Vdc supply (typical 5.0 V) with ≤10 mA current draw. A 100 nF ceramic capacitor must be placed between VS and GND near the device. Because the MPXHZ6115A6U is ratiometric, sharing the same 5 V regulator with the downstream ADC improves system accuracy by eliminating supply-induced gain errors-this configuration is explicitly validated in the MPXHZ6115A6U datasheet application circuits.
How does the MPXHZ6115A6U differ from the MPXH6115A6U?
The MPXHZ6115A6U includes fluorosilicone gel isolation for enhanced media resistance, while the MPXH6115A6U uses the same super small outline package (Case 98ARH99066A) but is rated only for dry air. Both share identical electrical specifications and pinout, but the MPXHZ6115A6U is qualified for automotive fluids and high-humidity environments-making it the appropriate choice where the MPXHZ6115A6U's gel protection is required for long-term reliability.
