FXLS8471Q - Linear Accelerometer

General Description

FXLS8471Q is a small, low-power, 3-axis, linear accelerometer in a 3 mm x 3 mm x 1 mm QFN package.

FXLS8471Q has dynamically selectable acceleration full-scale ranges of ±2 g/±4 g/±8 g and 14 bits of resolution.

Output data rates (ODR) are programmable from 1.563 Hz to 800 Hz.

Key Features

  • 1.95 V to 3.6 V VDD supply voltage, 1.62 V to 3.6 V VDDIO voltage.

FXLS8471Q 3-Axis, Linear Accelerometer Rev. 3.0 — 13 June 2019 Product data sheet 1 General description FXLS8471Q is a small, low-power, 3-axis, linear accelerometer in a 3 mm x 3 mm x 1 mm QFN package. FXLS8471Q has dynamically selectable acceleration full-scale ranges of ±2 g/±4 g/±8 g and 14 bits of resolution. Output data rates (ODR) are programmable from 1.563 Hz to 800 Hz. I2C and SPI serial digital interfaces are provided along with several user programmable event detection functions that can be used to reduce the overall system power consumption by off-loading the host processor. FXLS8471Q is guaranteed to operate over the extended temperature range of –40 °C to +105 °C. 2 Features and benefits • 1.95 V to 3.6 V VDD supply voltage, 1.62 V to 3.
