The sensor provides an extended g-range up to +/- 16g, higher resolution embedded wake-up function down to 3.9mg, and a 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.",
