L3GD20H屬于傳感器變送器的運動傳感器-陀螺儀。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的L3GD20H運動傳感器 - 陀螺儀陀螺儀運動傳感器 IC 和模塊用于測量或保持一個或多個軸上的方向和角速度。軸可能包括 X（俯仰）、Y（翻滾）和 Z（偏航），旋轉(zhuǎn)范圍從 100 到 6000 度。陀螺儀可根據(jù)靈敏度、模擬或數(shù)字、電源電壓、外殼樣式和輸出類型（例如模擬、I2C 和 SPI）進(jìn)行選擇。

描述 Description

The L3GD20H is a low-power three-axis angular

rate sensor.

It includes a sensing element and an IC interface

able to provide the measured angular rate to the

external world through digital interface (I2C/SPI).

The sensing element is manufactured using a

dedicated micromachining process developed by

ST 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 L3GD20H has a full scale of

±245/±500/±2000 dps and is capable of

measuring rates with a user selectable

bandwidth.

The L3GD20H is available in a plastic land grid

array (LGA) package and can operate within a

temperature range from -40 °C to +85 °C.
