Three-axis, ±400g digital accelerometer for high-shock capture
The ADXL373BCCZ-RL7 from Analog Devices is a micropower, three-axis digital accelerometer that measures X, Y, and Z acceleration up to ±400g with a sensitivity of 5 LSB/g. It is designed for high-shock event monitoring in industrial and automotive environments where standard ±200g parts would clip. Built-in features include adjustable bandwidth from 160 Hz to 2.56 kHz, a sleep mode for battery-powered impact loggers, and an integrated temperature sensor for compensation.
Active lifecycle — no LTB pressure
ROHS3 compliance is confirmed. This is a part you can qualify into a new design without worrying about a forced redesign mid-cycle.
I²C and SPI — direct MCU connection
Both I²C and SPI interfaces are available, selectable by the chip-select pin. I²C is simpler for low-pin-count microcontrollers; SPI offers higher data rates for burst reads of all three axes. The adjustable bandwidth (160 Hz to 2.56 kHz) lets you filter out high-frequency vibration noise when measuring gross acceleration events. Sleep mode draws minimal quiescent current — the part wakes on a threshold event, records the peak, and can return to sleep, making it practical for battery-powered event loggers that must last months in the field.
