Rohm Semiconductor KXT Series Tri-Axis Accelerometers

Kionix Rohm Semiconductor KXT Series Tri-Axis Accelerometers feature a high-resolution wake-up function with a threshold configurable down to 3.9mg. The KXT tri-axis accelerometers are available in extended user-configurable G-ranges ±2g, ±4g, ±8g, and ±16g. These accelerometers operate at temperatures ranging from -40°C to +85°C and also offer a supply voltage range of 1.71V to 3.6V. KXT tri-axis accelerometers come with user-configurable output data rates from 0.781Hz to 1600Hz. Typical applications include aerospace, automotive, defense, gaming, industrial machinery, medical devices, sports and fitness.
