Note:
TYPICAL PERFORMANCE CURVES
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.
Note: Unless otherwise specified, DV DD , AV DD = 5V; A GND , D GND = 0V; V REF = Internal, HPF = 1 (AC mode),
MCLK = 3.58 MHz.
