产品概览
The ADXL346ACCZ-RL7 is a 3-axis digital accelerometer from Analog Devices with 16-bit resolution and selectable measurement ranges of +/-2g, +/-4g, +/-8g, or +/-16g. It features a SPI/I2C digital interface, integrated FIFO buffer, and programmable activity/inactivity detection. The LGA package measures only 3x3x1mm, making it ideal for portable and space-constrained motion sensing applications.
