Selection Guide

Choose the LSM6DS3TR when you need a proven, cost-effective IMU with a large FIFO and low power consumption for consumer and industrial applications. If you require the lowest possible noise and additional features like a sensor hub, consider the LSM6DSO, but be prepared for a higher cost and smaller FIFO.

Design Notes

Place a 100nF ceramic capacitor as close as possible to the VDD pin and a 1uF capacitor in parallel for bulk decoupling. The LSM6DS3TR operates from 1.71V to 3.6V, so ensure the supply is stable and free of noise, especially in battery-powered designs. A low-dropout regulator (LDO) is recommended to provide a clean supply if the input voltage varies.

Route the I2C/SPI lines with controlled impedance and keep them short to minimize noise. Use pull-up resistors (typically 4.7kΩ) on the I2C lines. The CS pin must be tied high for I2C mode or low for SPI mode. Ensure the SA0 pin is set to the desired I2C address before power-up. The LGA-14 package has a 0.5mm pitch, so use a stencil with appropriate aperture for soldering.

Do not leave the INT1 and INT2 pins floating; configure them as push-pull or open-drain with pull-ups as needed. The reserved pins (9-12) must not be connected to any trace or via. Avoid placing the sensor near high-frequency switching components or strong magnetic fields, as this can affect measurement accuracy. Ensure the device is mounted flat to avoid mechanical stress that could cause offset errors.
