MEMS motion sensor: 3-axis digital gyroscope

The L3GD20 is a low-power three-axis angular rate sensor.

It includes a sensing element and an IC interface capable of providing the measured angular rate to the external world through a digital interface (I2C/SPI).

The sensing element is manufactured using a dedicated micro-machining process developed by STMicroelectronics to produce inertial sensors and actuators on silicon wafers.

The IC interface is manufactured using a CMOS process that allows a high level of integration to design a dedicated circuit which is trimmed to better match the sensing element characteristics. The L3GD20 has a full scale of ±250/±500/ ±2000 dps and is capable of measuring rates with a user-selectable bandwidth.

The L3GD20 is available in a plastic land grid array (LGA) package and can operate within a temperature range of -40 °C to +85 °C.
