CMA3000 Accelerometers
Ultra Small Size, Low Power 3-axis
Accelerometer
CMA3000-D01 with digital SPI and I2C
interfaces is optimised for systems requiring ultra low power. It has user
selectable frequency response and ultra low 770 uA current consumption.
Interrupt signal can be triggered by data ready, motion and free fall.
