ST LSM320HAY30 3D數(shù)字線性加速度傳感方案
加入技術(shù)交流群
The LSM320HAY30 is a low-power system-in-package featuring a 3D digital linear acceleration sensor and a 2D analog angular rate pitch and yaw sensor. It provides excellent temperature stability and high resolution over an extended operating temperature range (-40℃to +85℃).
ST’s family of sensor modules leverages the robust and mature manufacturing process already used for the production of micromachined accelerometers. The LSM320HAY30 has a dynamically user-selectable full-scale acceleration range of ±2 g/±4 g/±8 g, and an angular rate of ±300 dps capable of detecting rates with a -3 dB bandwidth up to 140 Hz along pitch and yaw axes. The LSM320HAY30 is capable of measuring linear accelerations with output data rates from 0.5 Hz up to 1 kHz. The embedded self-test capability allows the user to check the functioning of each sensor in the final application. The device can be configured to generate an interrupt signal by inertial wakeup/free-fall events as well as by the position of the device itself. Several years ago ST successfully pioneered the use of this package for accelerometers. Today, ST has the widest manufacturing capability and strongest expertise in the world for production of sensors in plastic LGA packages.
