The KXTJ2 is our smallest tri-axis accelerometer, designed for mobile applications. It offers our best power performance along with an embedded wake-up feature, Fast-mode I2C  and up to 14-bit resolution. The KXTJ2 is delivered in a 2 x 2 x 0.9 mm, 12-pin, LGA package with an operating temperature range of -40°C to +85°C. The KXTJ2 sensor offers improved shock, reflow, and temperature performance, and the ASIC has internal voltage regulators that allow operation from 1.8 V to 3.6 V within the specified product performance.
