Electrical Characteristics
All voltages are reference to ground. Currents flowing into the circuit have positive values.
The absolute maximum ratings of the CMA3000 are presented in Table 8 below.

* 1 m drop on concrete may cause >>10000 g shock.
Please refer to the corresponding product datasheet.
Table 9. DC characteristics of digital I/O pins.
All the CMA3000 products have an internal level shifter that can be used to interface e.g. a micro
controller using lower supply than the CMA3000. 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.
