KXCJ9-1018
Tri-Axis, User Selectable ± 2g, 4g, 8g, 16g Digital (I2C) Output, 3x3x0.9mm LGA - KXCJ9-1018

The KXCJ9 is a high-performance, ultra-low-power, 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 KXCJ9 is delivered in a 3 x 3 x 0.9 mm, 10-pin, LGA package with an operating temperature range of -40°C to +85°C. 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.
