Notes:

1. Functional and tested operating conditions are given in Table 2. Absolute maximum ratings are stress ratings only, and

functional operation at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability or cause.

2. (M,L,O)VIN, and MVREF may overshoot/undershoot to a voltage and for a maximum duration as shown in Figure 2.
