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

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.

Features:

  • Low current consumption: < 1 µA in standby, 10 µA at low resolution, and 135 µA at high resolution
  • Internal voltage regulator
  • 8-bit, 12-bit, and 14-bit resolution
