It offers our best power performance along with an embedded wake-up feature, Fast-mode I2C and up to 14-bit resolution. The KXCJ9 is delivered in a 3 x 3 x 0.9 mm, 10-pin, LGA package with an operating temperature range of -40C to +85C. The KXCJ9 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. Pin compatible with KXTI9 and KXTF9. KXCJ9 Accelerometer 3x3x0.9mm Low-Power Accelerometer The performance parameters below are programmed and tested at 2.6 volts and T = 25C. 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.
