GENERAL DESCRIPTION

The ADXL212 is a high precision, low power, complete dual axis accelerometer with signal conditioned, duty cycle modulated outputs, all on a single monolithic IC. The ADXL212 measures acceleration with a full-scale range of ±2 g (typical). The ADXL212 measures both dynamic acceleration (such as vibration) and static acceleration (such as gravity).
