PRODUCT OVERVIEW  
The KXTJ2 is one of our smallest tri-axis accelerometers,  
designed for mobile applications. It offers excellent power  
performance along with an embedded motion 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.  
KXTJ2 Accelerometer  
2x2x0.9mm Low-Power Accelerometer  
The performance parameters below are programmed and tested at 2.6 volts and T = 25°C. The device can accept supply voltages from 1.8V to  
3.6V. Due to internal voltage regulators, there should be minimal change with supply voltage variations.
