Tri-Axis, User Selectable 2g, 4g, 8g, Digital (I²C) Output, 3x3x0.9mm LGA - KXTF9-2050

The KXTF9 is a very popular high-performance, low-power, tri-axis digital I²C accelerometer with integrated orientation, Directional tap/double-tap, activity monitoring and motion-detection algorithms. The KXTF9 offers user-selectable ranges of ±2g, ±4g or ±8g as well as 8-bit and 12-bit resolution. The KXTF9 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 KXTF9 operates from a 1.8 V to 3.6 V DC supply (factory-programmable).

Not Recommended for New Designs.
