DESCRIPTION

· The KX134-1211 is a tri-axis accelerometer with configurable ranges of ±8g, ±16g, ±32g, or ±64g.

· It features a 3-stage Advanced Data Path (ADP) including low-pass, low-pass/high-pass filters, and an RMS calculation engine.

· The accelerometer includes Wake-Up and Back-to-Sleep detection with a threshold configurable down to 15.6 mg.

· It has a 512-byte buffer that records data continuously, even during read operations.

· The device supports I²C or SPI digital protocols for configuration and data output.

· It is housed in a 2 x 2 x 0.9 mm LGA 12-pin package and operates from 1.7V to 3.6V.

FEATURES

· Operating temperature range from -40ºC to +105ºC.

· User-configurable g-range up to ±64g and Output Data Rate up to 25600 Hz.

· High-resolution Wake-Up/Back-to-Sleep functions with a threshold configurable down to 15.6 mg.

· Integrated Free fall, Directional-TapTM/Double-TapTM, and Device-orientation algorithms.

· Embedded 512-byte FIFO buffer that continues to record data even when being read.

· Internal voltage regulator for stable operation over varying supply voltages.

· Digital I2C up to 3.4MHz and Digital SPI up to 10MHz.

APPLICATIONS

· Suitable for applications requiring precise motion detection and analysis.

· Ideal for use in consumer electronics, industrial controls, and automotive systems.

· Effective in devices needing orientation, tap, and free-fall detection.

· Useful in systems requiring continuous data recording and monitoring.

· Applicable in environments with varying temperatures and high shock survivability.
