Table 3-1. Recommended Operating Conditions

GNDA = GNDP = 0 V, all voltages with respect to ground. Device functional operation is guaranteed within these limits. Functionality is not guaranteed

or implied outside of these limits. Operation outside of these limits may adversely affect device reliability.
