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.
FOR
 Smartphones and Mobile Devices
 Laptops
 Gaming and Virtual Reality
 Health and Fitness
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.
