Product electrical ratings
3.1
Operating range
Within the operating range the part operates as specified and without parameter deviations. The device may not
operate properly if maximum operating conditions are exceeded.
Once taken beyond the operative ratings and returned back within, the part will recover with no damage or
degradation, unless the AMR are exceeded.
Additional supply voltage and temperature conditions are given separately at the beginning of each electrical
specification table.
All voltages are related to the potential at substrate ground AGND, unless otherwise noted.
