STMicroelectronics (ST) introduced the LIS344AL, an ultra compact consumer low power 3-axis linear accelerometer that includes a sensing element and an IC interface. The single-package approach protects a robust three-axis Micro Electro Mechanical System (MEMS) sensor and a CMOS interface chip that provides tilting and motion information, independent of the device’s orientation.

Key Features of ST’s LIS344AL Accelerometer:

  •  Single voltage supply operation
  •  Output voltage, offset and sensitivity are ratiometric to the supply voltage
  •  ±3.5g full-scale
  •  Factory trimmed device sensitivity and offset
  •  Embedded self test
  •  High shock survivability (10000g)
  •  RoHS/ECOPACK compliant

The LIS344AL accelerometer provides shock survivability up to 10,000g. It estimates acceleration values at a very low noise level with minimized power consumption, which is especially critical in battery-operated portable systems.

The LIS344AL accelerometer offers a full-scale output range of +/-3.5g. The built-in self-test facility allows the user to verify both the mechanical and electrical parts of the device. The accelerometer uses ST’s ECOPACK lead-free technology for RoHS-compliance.

The LIS344AL accelerometer is capable of measuring accelerations over a maximum bandwidth of 2.0kHz. The device bandwidth may be reduced by using external capacitances. A self-test capability allows the user to check the functioning of the system.

The LIS344AL accelerometer is available in Land Grid Array package (LGA) and it is guarantee to operate over an extended temperature range of -40°C to +85°C.

LIS344AL accelerometer is housed in a 4 x 4 x 1.5mm plastic package. Price: $1.40 for large volumes
