ADXL322:  Small and Thin ± 2g Accelerometer

Product Description

The ADXL322 is an ultra small package (4 x 4 x 1.45 mm LFCSP) and low power (340 µA at Vs = 2.4V) ± 2g iMEMS® accelerometer designed to accommodate the integration requirements of mobile phones and other portable devices for a variety of motion, tilt, and inertial sensing features (e.g., data entry, menu and display control, power management, situational awareness, navigation, and portrait vs. landscape display orientation). The ADXL322 also enables hard disk drive protection systems and security features in notebook computers, as well as position and tilt sensing for PC and gaming peripherals such as mouse and joystick devices.
