Introduction

This document is intended to provide information on the use of, and application hints related to, ST’s L3GD20H 3-axis digital gyroscope.

The L3GD20H is a 3-axis angular rate sensor with a digital I2C/SPI serial interface standard output.

The device has a full scale of ±245/±500/±2000 dps and is capable of measuring rates with a user-selectable bandwidth.

The device may be configured to generate interrupt signals by detecting an independent wake-up event. Thresholds and timing of the interrupt generator are programmable by the end user on the fly.

The L3GD20H has an integrated 32-level first in first out (FIFO) buffer allowing the user to store data in order to limit intervention by the host processor.

The L3GD20H is available in a small thin plastic land grid array package (LGA-16 3x3x1) and it is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.

The ultra-small size and weight of the SMD package make it an ideal choice for handheld portable applications such as smartphones, wearables or any other application where reduced package size and weight are required.
