Application note
L3GD20H: 3-axis digital output gyroscope
By Michele Ferraina
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 I
2
C/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.
