STMicroelectronics AIS328DQ Triaxial Accelerometer

The AIS328DQ is a state-of-the-art triaxial accelerometer designed by STMicroelectronics, tailored to deliver high-performance motion sensing across a wide spectrum of applications. This robust sensor is particularly suited for automotive applications, meeting the stringent requirements for non-critical safety applications within the vehicle dynamics domain.

With its advanced MEMS (Micro-Electro-Mechanical Systems) technology, the AIS328DQ provides precise acceleration detection in three dimensions: X, Y, and Z axes. This makes it an ideal component for a variety of uses, such as vehicle impact sensing, vehicle dynamic control, and tilt/inclination measurement in industrial and consumer electronics.

The AIS328DQ operates within an extended temperature range of -40°C to +105°C, ensuring reliable performance in harsh environmental conditions. Its wide supply voltage range from 2.4 V to 3.6 V offers flexibility in system design, making it a versatile solution for integration into various electronic systems.

Key features of the AIS328DQ include:

• High Measurement Range: The device is capable of measuring accelerations up to ±2g/±4g/±8g, providing ample range for most dynamic applications.
• High Resolution: The accelerometer boasts a 16-bit data output, which allows for precise and high-resolution measurements.
• Digital Interface: The sensor comes with a SPI/I2C serial digital interface, ensuring easy integration with most microcontrollers and processors.
• Programmable Interrupts: It offers two independent programmable interrupt generators for free-fall and motion detection, enhancing its utility in safety-critical applications.
• Embedded Self-Test: The AIS328DQ includes an embedded self-test capability that allows the user to verify the functioning of the sensor after it has been assembled onto a system.

The AIS328DQ is delivered in a small, lead-free, 16-pin plastic land grid array (LGA) package which is designed for optimized footprint and weight considerations, making it suitable for space-constrained designs. Its robustness, combined with STMicroelectronics' proven expertise in MEMS sensor technology, makes the AIS328DQ a reliable choice for designers looking to incorporate advanced motion sensing capabilities into their automotive or industrial applications.
