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. 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. |The performance parameters below are programmed and tested at 2.6 volts and T = 25°C.
