TYPICAL PERFORMANCE CHARACTERISTICS
The graphs provided following this note are a statistical summary based on a limited number of samples
and are provided for informational purposes only. The performance characteristics listed herein are not
tested or guaranteed. In some graphs, the data presented may be outside the specified operating range
(e.g., outside specified power supply range) and therefore outside the warranted range.
