Overview
The L3GD20TR, produced by STMicroelectronics, is a low-power three-axis angular rate sensor. It incorporates a sensing element and an IC interface, enabling the measurement of angular rates and their transmission to the external world through a digital interface (I2C/SPI). The sensing element is manufactured using a dedicated micro-machining process, while the IC interface is produced using a CMOS process, allowing for high integration and precise matching with the sensing element characteristics. This sensor is particularly notable for its low power consumption, user-selectable full scales (±250/±500/±2000 dps), and extended operating temperature range (-40 °C to +85 °C).
