TYPICAL PERFORMANCE CURVES

Note: Unless otherwise specified, TA = +25°C, VDD = 5V, VREF = 2.5V, VSS = 0V, VCM = VREF/2, VIN+ = VIN-.

All ppm units use 2*VREF as full-scale range. Unless otherwise noted, graphs apply to entire MCP3551/3 family.

Note:

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.
