Overview

The MPXH6115AC6U is a high-integration absolute pressure sensor designed for applications requiring precise atmospheric or manifold pressure monitoring. It features an on-chip bipolar op-amp and a thin-film resistor network to provide a high-level analog output signal and temperature compensation from -40 C to +125 C. The small footprint surface-mount package includes a vertical port for easy tubing connection.

Why Choose This Part

This sensor offers an extremely low maximum error of 1.5 percent over the 0 C to 85 C temperature range, ensuring high reliability in varying environments. Its high sensitivity of 45.0 mV/kPa provides excellent signal resolution for 10-bit microcontroller ADCs without needing additional external amplification.

Applications

Barometric Pressure Measurement
Ideal for weather stations and altitude sensing due to its 15 kPa to 115 kPa measurement range.
Engine Control Systems
Used for Manifold Absolute Pressure (MAP) sensing to optimize fuel injection and ignition timing.
Industrial Process Control
Suitable for pneumatic systems and pressure-regulated equipment where high humidity resistance is required.

Getting Started

To integrate this sensor, provide a stable 5.0 V supply and connect the analog output directly to a microcontroller ADC pin. A 0.1 uF decoupling capacitor should be placed near the Vcc pin, and a simple RC low-pass filter on the output is recommended to reduce noise in high-vibration automotive environments.
