What this part is and where it fits
The ADXL203CE-REEL is a dual-axis analog accelerometer from Analog Devices' iMEMS® family, sensing acceleration along the X and Y axes with an analog voltage output. It covers a ±1.7 g range and delivers 1000 mV/g sensitivity — high enough that many ADC inputs can read the output directly without a gain stage. Bandwidth is user-selectable via external capacitors from 0.5 Hz up to 2.5 kHz, so the same part can serve low-frequency tilt sensing or moderate-bandwidth vibration monitoring. The 8-CLCC package (5x5 mm) is surface-mount rated for -40°C to 125°C operation, making it suitable for industrial control, automotive under-hood, and outdoor instrumentation environments where temperature extremes are routine.
Temperature range and deployment context
Rated from -40°C to 125°C, the ADXL203CE-REEL covers the full industrial and extended automotive temperature envelope. That means it can sit in an engine bay, on a hydraulic pump, or inside an outdoor telecom cabinet without derating for ambient heat. The 8-CLCC ceramic package also handles the thermal cycling of these environments better than plastic overmold packages — less package-induced stress on the MEMS element over thousands of thermal cycles.
Sourcing and lifecycle
For dual-sourcing flexibility, the AD22293Z-RL7 is a functional peer from the same iMEMS® family, though it shifts to a ±5 g range with 312 mV/g sensitivity — verify the range match before substituting.
