Overview
The ADXL363BCCZ-RL7, produced by Analog Devices Inc., is an ultralow power, three-sensor combination device. It integrates a 3-axis MEMS accelerometer, a temperature sensor, and an on-board analog-to-digital converter (ADC) for synchronous conversion of an external signal. This device is designed for applications requiring low power consumption and high precision sensing. It operates within a wide supply voltage range of 1.6 V to 3.5 V and is packaged in a small and thin 3 mm × 3.25 mm × 1.06 mm LGA package.
