The ADXL320/321 family of ±0.5-g iMEMS accelerometers are dual-axis units housed in thin 4- by 4- by 1.45-mm plastic lead-frame chip-scale packages (LFCSPs). Featuring signal-conditioned outputs, the devices are aimed at demanding consumer applications. They operate from supplies as low as 2.7 V dc and typically draw 450 µA. Typical noise floor is 200 µg per root Hz, allowing small tilt changes to be sensed using the narrow bandwidths (less than 10 Hz) typical of human motion. In sample quantities, the ADXL430/321 accelerometers each cost $2.40. Production quantities will be available in the third quarter.
