Product details
Overview
MPXAZ6115A6U from Freescale Semiconductor is an absolute pressure sensor IC with 15–115 kPa full-scale range, ratiometric analog output (0.200 V to 4.700 V at 5.0 V supply), ±1.5% VFSS accuracy over 0 °C to 85 °C, and on-chip temperature compensation from −40 °C to +125 °C. It serves as a signal-conditioned transducer in engine manifold absolute pressure (MAP) sensing and barometric measurement systems.
For engineers reviewing the MPXAZ6115A6U datasheet, MPXAZ6115A6U pinout, MPXAZ6115A6U application, or MPXAZ6115A6U equivalent, this page delivers verified package mapping (Case 98ASB17756C), confirmed pin functions (VS/VOUT/GND), calibrated transfer function (VOUT = VS × (0.009×P − 0.095)), and validated alternatives for automotive and industrial pressure-sensing designs.
Technical Context
The MPXAZ6115A6U integrates a piezoresistive silicon diaphragm with monolithic bipolar op-amp circuitry and thin-film resistor networks to deliver a high-level analog output directly proportional to absolute pressure. Its architecture includes on-die temperature compensation and factory calibration across the operating temperature range.
This sensor operates ratiometrically with a 4.75–5.25 Vdc supply, draws 6.0–10 mA typical supply current, and features fluorosilicone gel isolation for media resistance. Output response time is 1.0 ms (10%–90%), and warm-up time is ≤20 ms after pressure stabilization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 15–115 kPa absolute - defines usable input range for MAP and barometric applications without saturation. |
| Supply Voltage | 4.75–5.25 Vdc - enables direct interface with standard 5 V microcontroller systems and ensures ratiometric stability. |
| Output Voltage Range | 0.200–4.700 Vdc at VS = 5.0 V - provides >4.5 V full-scale span for high SNR ADC digitization. |
| Accuracy | ±1.5% of full-scale span (VFSS) over 0 °C to 85 °C - guarantees calibrated performance in under-hood and weather station environments. |
| Operating Temperature | −40 °C to +125 °C - supports placement in engine compartments and industrial enclosures without external thermal management. |
| Response Time | 1.0 ms (10%–90%) - enables real-time dynamic pressure capture in fast-changing intake manifolds. |

Pinout & Package
MPXAZ6115A6U uses the small outline package Case 98ASB17756C (8-pin SOP), with pin 1 identified by a chamfered corner. The package is thermoplastic (PPS), surface-mount compatible, and qualified for automotive-grade reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DNC | Do not connect - electrically isolated; used only for mechanical alignment and pin 1 identification. |
| 2 | VS | Voltage supply input - accepts 4.75–5.25 Vdc; powers internal amplifier and compensation circuitry. |
| 3 | GND | Analog ground reference - must be low-impedance and separated from digital ground to minimize noise coupling. |
| 4 | VOUT | Analog output - delivers ratiometric voltage proportional to absolute pressure; interfaces directly to 10–12-bit ADC inputs. |
| 5–8 | DNC | Do not connect - no internal connection; must remain floating per datasheet specification. |
Key Features

FAQ
What is the absolute pressure range supported by the MPXAZ6115A6U?
The MPXAZ6115A6U supports an absolute pressure range of 15 kPa to 115 kPa. This range is referenced to a sealed vacuum cavity inside the sensor die and is optimized for applications such as manifold absolute pressure (MAP) sensing and barometric pressure measurement. Operation outside this range may cause output saturation or reduced linearity, and the device is rated for a maximum pressure of 400 kPa without permanent damage.
Does the MPXAZ6115A6U require external temperature compensation?
No, the MPXAZ6115A6U does not require external temperature compensation. It incorporates on-chip temperature compensation circuitry that maintains accuracy across −40 °C to +125 °C. The datasheet confirms full compensation from −40 °C to +125 °C, with ±1.5% VFSS accuracy specified over 0 °C to 85 °C - eliminating the need for external thermistors or software correction algorithms in most implementations.
What is the supply voltage requirement for stable operation of the MPXAZ6115A6U?
The MPXAZ6115A6U requires a supply voltage of 4.75 Vdc to 5.25 Vdc for stable, ratiometric operation. At VS = 5.0 Vdc, it delivers a nominal output span of 4.500 V (from 0.200 V to 4.700 V). Supply current consumption is 6.0–10 mA typical, and the device is explicitly characterized for ratiometric behavior within this excitation range - deviations outside this window may affect accuracy and output linearity.
How is the MPXAZ6115A6U pinout configured, and which pins are functional?
The MPXAZ6115A6U uses an 8-pin small outline package (Case 98ASB17756C) with pin 1 identified by a chamfered corner. Only pins 2 (VS), 3 (GND), and 4 (VOUT) are functional; pins 1 and 5–8 are DNC (do not connect) and must remain unconnected. This configuration minimizes external component count and simplifies PCB layout, with GND serving as the analog reference for both supply and output.
Is the MPXAZ6115A6U suitable for use with automotive fluids or high-humidity environments?
Yes, the MPXAZ6115A6U is specifically designed for such environments. It features a fluorosilicone gel coating that isolates the silicon die and wire bonds from moisture and common automotive media including engine oil vapor and coolant mist. The datasheet states it is "resistant to high humidity and common automotive media," and qualification testing confirms long-term stability under cyclic pressure and temperature stress in these conditions.
