TYPICAL CHARACTERISTICS

The graphs and tables 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 or tables, the data presented may be outside the specified operating range (e.g., outside

specified power supply range) and therefore outside the warranted range.
