Typical Performance Curves
1.0 TYPICAL PERFORMANCE CURVES Note: The following performance graphs are for the devices that are documented in the MCP47FEBXX data
sheet (DS20005375A). This document allows the MCP47FEBXX data sheet’s functional description to be
in PDF format with a file size smaller than the 10 MB limit of many email file servers.
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 indicated, TA = +25°C, VDD = 5.5V.
