Description and Introduction

MEMS inertial sensor 3-axis ultracompact linear accelerometer The LIS344ALTR is a low-power three-axis linear accelerometer manufactured by STMicroelectronics (STM).  

### **Specifications:**  
- **Type:** MEMS (Micro-Electro-Mechanical Systems) accelerometer  
- **Axes:** 3-axis (X, Y, Z)  
- **Measurement Range:** ±2g / ±6g (selectable)  
- **Output Type:** Analog voltage  
- **Supply Voltage (Vdd):** 2.4V to 3.6V  
- **Current Consumption:** 0.5 mA (typical)  
- **Bandwidth:** Adjustable (up to 1.5 kHz)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** LGA-16 (3x5x1 mm)  

### **Descriptions and Features:**  
- **Low Power Consumption:** Optimized for battery-operated applications.  
- **High Sensitivity:** Suitable for motion detection and tilt sensing.  
- **Selectable Full-Scale Range:** Allows flexibility in measurement range (±2g or ±6g).  
- **Embedded Self-Test:** Enables functional verification.  
- **Shock Resistant:** Withstands high mechanical shocks (up to 10,000g).  
- **Analog Output:** Provides real-time acceleration data without digital processing.  
- **Compact Size:** Small footprint for space-constrained applications.  

This accelerometer is commonly used in industrial, automotive, and consumer electronics for motion sensing, vibration monitoring, and orientation detection.

Application Scenarios & Design Considerations

MEMS inertial sensor 3-axis ultracompact linear accelerometer

Alternative Part Number

  • ADXL335BCPZ --: Tri-axis analog accelerometer with similar ±3g range and analog output, widely used as a drop-in functional replacement for the LIS344AL.
  • MMA7361LC --: Tri-axis analog accelerometer with selectable ±1.5g/±6g range and low power consumption, suitable for similar motion-sensing applications.
  • KXTC9-2050 --: Tri-axis analog accelerometer with ±2g range and compact package, offering comparable performance for consumer motion-sensing designs.
  • LIS3DH --: Same manufacturer three-axis accelerometer with digital I2C/SPI output; requires interface change but offers equivalent sensing capability and long-term availability.
