Electrical Characteristics
Angular rate output registers are refreshed when the address of the output register is written. Use
decrement reading to ensure XYZ data from the same moment.
All voltages are reference to ground. Currents flowing into the circuit have positive values.
The absolute maximum ratings of the CMR3000 are presented in Table 4 below.

Exposure to ultrasonic energy
(e.g. ultra sonic washing or
welding)
* 1 m drop on concrete may cause >>10000 g shock.
Please refer to the corresponding product datasheet.
Table 5. DC characteristics of digital I/O pins.
All the CMR3000 products have an internal level shifter that can be used to interface e.g. a micro
controller using lower supply than the CMR3000. The level shifter is "programmed" by providing the
supply voltage of the interfaced device to the DVIO-pin. Please refer to the corresponding product
data sheet for details.
