Three-axis gyroscope

  • 27-Feb-2012 02:13 EST

STMicroelectronics offers the market’s first three-axis digital-output gyroscope that meets the industry-standard qualification for automotive integrated circuits (AEC-Q100). The company’s A3G4250D angular-rate sensor intends to add positioning accuracy and stability to a wide range of automotive applications, including in-dash navigation, telematics, and vehicle tolling systems. The 3-V single-supply sensor measures angular rates up to ±250 degree per second. An on-chip IC interface converts the angular-motion data into a 16-bit digital bit stream that is transmitted with high reliability to a dedicated microcontroller chip through a standard serial peripheral interface or I(2)C protocol. Operating within an extended temperature range from -40­° to +85°C (-40° to +185°F), the device embeds an 8-bit temperature sensor.
