LIS3DHTR in ST LSM / LIS IMU & Accelerometers Family
The LIS3DHTR is a high-performance, ultra-low-power three-axis linear accelerometer belonging to the STMicroelectronics 'femto' family. It utilizes MEMS technology to provide selectable full-scale ranges of ±2g, ±4g, ±8g, or ±16g with an integrated 16-bit ADC. This sub-family is a staple in the embedded industry for low-power motion sensing, offering an excellent balance of power efficiency, noise performance, and cost-effectiveness for battery-operated consumer and industrial electronics.
Variants in This Sub-Family
Variants within the LIS3DH sub-family primarily differ by their packaging, temperature ratings, and qualification levels. While the standard LIS3DHTR uses a 16-lead LGA package, automotive-grade versions (prefixed with AIS) provide enhanced reliability and stricter testing protocols. Some derivatives may feature slight variations in internal noise floors or output data rate options to target specific cost-sensitive or performance-critical application niches.
