Additional Details

The ADXL321JCPZREEL7 outputs analog voltages proportional to the acceleration in each axis. These voltages can be directly read by a microcontroller or ADC. The device operates from a single 3V to 5V power supply. The bandwidth of the accelerometer can be adjusted using external capacitors, allowing users to optimize the noise performance for their specific application. The sleep mode reduces power consumption to a few microamps when the device is not actively sensing. It is supplied in a small, thin, 3x5x1 mm LFCSP package. Care should be taken during soldering to avoid overheating the device. Proper decoupling capacitors should be used to minimize noise on the power supply lines.
