MEMS inertial sensor: High Full-Scale, High Bandwidth, Low-Noise Analog Accelerometer
  • Target 目标

The LIS344AHH is a high-performance, high-bandwidth, low-noise three-axis linear accelerometer that includes a sensing element and an IC interface able to take information from the sensing element and provide an analog signal to the external world.

The sensing element, capable of detecting linear acceleration, is manufactured using a dedicated process developed by ST to produce inertial sensors and actuators in silicon.

The IC interface is manufactured using an ST proprietary CMOS process with a high level of integration. The dedicated circuit is trimmed to better match the characteristics of the sensing element.

The LIS344AHH has a user-selectable full scale of ±6 g or ±18 g and it is capable of measuring accelerations over a high bandwidth of 2.5 kHz for all axes. The device bandwidth may be reduced by using external capacitances.

The self-test capability allows the user to check the functioning of the system.

The LIS344AHH is available in a land grid array package (LGA) manufactured by ST.It is guaranteed to operate over an extended temperature range of -40 °C to +85 °C.
