ROHM Semiconductor – KXTJ3: User Selectable ±2g, 4g, 8g, 16g Tri-Axis Accelerometer with Digital Interface


The KXTJ3 is the next generation of our best-selling KXTJ2 tri-axis accelerometer that provides the best value and high performance available in the same pin-to-pin compatible 2 x 2 x 0.9mm 12-pin LGA package. New and improved is an extended g-range up to ±16g, higher resolution embedded wake-up function down to 3.9mg, and more flexible interrupt circuitry. The KXTJ3 sense element offers lower noise performance, exceptional shock resiliency, stable performance over temperature, and virtually eliminates offset and sensitivity shifts from reflow.
