What this accelerometer brings to a retrofit or new design
The ADXL357BEZ-RL7 is a 3-axis digital accelerometer from Analog Devices that covers ±10g, ±20g, and ±40g ranges — selectable per axis via the digital interface. That means one part number can handle everything from low-g tilt sensing in a solar tracker to high-g vibration monitoring on a conveyor drive, without requalifying a second package. It talks I²C or SPI on the same pins, so you can drop it into an existing 2-wire bus or a faster 4-wire link with no board respin. The output is digital, which keeps noise out of the analog path when the sensor sits far from the MCU.
Selectable scale and sensitivity trade-offs
Sensitivity runs from 51200 LSB/g at ±10g down to 12800 LSB/g at ±40g. If you need fine resolution for a low-vibration bearing monitor, the ±10g range gives you the most counts per g. For a shock event recorder, the ±40g range keeps the output from clipping. The adjustable bandwidth goes from 1 Hz to 1 kHz via the digital filter, so the same part can serve a slow tilt application (low-pass at 10 Hz) and a fast vibration analysis (1 kHz) by changing a register.
Active production — no LTB pressure
The 14-lead CLCC package is a standard footprint — no exotic pad geometry.
