STMicroelectronics – LIS2HH12 new 3-axis accelerometer featuring high resolution, high stability over temperature, housed in a 2×2 package

It is well adapted for Industrial and Home Appliance (vibration analysis, inclinometer, gesture recognition…) where high temperature stability is required associated with precise temperature compensation, filter capabilities, long lifetime and a cost effective solution. LIS2HH12 offers very accurate and stable measurements thanks to the low Zero-g level offset of ±30 mg, low temperature impact on acceleration sensitivity (±0.01 %/°C) and Zero-g level change vs. temperature (±0.25 mg/°C).

LIS2HH12 is pin to pin compatible with the well-known LIS2DH12 (2×2 mm² – 12 bit resolution). It can easily be replaced by 6-axis E-compass LSM303C/E (same pinout structure, easy software upgrade).

Feature:

  • ±2/±4/±8 linear acceleration full scale
  • Offset accuracy : ±30mg
  • Zero-g level change vs temperature : ±0.25mg/°C
  • Sensitivity change vs temperature : ±0.01 %/°C
  • 16-bit data output
  • SPI / I2C serial interfaces
  • Wide supply voltage 1.71 V to 3.6 V
  • ODR selectable : 10 to 800 Hz
  • 2 Programmable interrupt generators enabling Intelligent power saving
  • Embedded self-test & FIFOs
  • Embedded temperature sensor (8 digit/°C)
  • Low consumption : 50 µA typical @ 10 Hz
  • Very small package (LGA-12, 2x2x1 mm²)

LIS2HH12 is now available in mass production.

Sensor fusion software library & tools are available.
