MCP3550/1/3 - Microchip

MCP3550/1/32.0 TYPICAL PERFORMANCE CURVESNote:The graphs and tables provided following this note are a statistical summary based on a limited number ofsamples and are provided for informational purposes only. The performance characteristics listed hereinare not tested or guaranteed. In some graphs or tables, the data presented may be outside the specifiedoperating range (e.g., outside specified power supply range) and therefore outside the warranted range.Note: Unless otherwise specified, T A = +25°C, V DD = 5V, V REF = 2.5V, V SS = 0V, V CM = V REF /2, V IN + = V IN -.All ppm units use 2*V REF as full scale range. Unless otherwise noted, graphs apply to entire MCP3550/1/3 family.INL (ppm)54+125 C32+85 C10-1-40 C-2+25 C-3-4-5-2.5 -1.5 -0.5 0.5 1.5 2.5V IN (V)INL Error (ppm)10864200 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5V REF (V)FIGURE 2-1:(V DD = 2.7V).INL Error vs. Input VoltageFIGURE 2-4:V REF .Maximum INL Error vs.INL (ppm)54+125 C3+85 C210-1- 40 C-2+25 C-3-4-5-2.5 -1.5 -0.5 0.5 1.5 2.5V IN (V)Max INL (ppm)109876543210-50 -25 0 25 50 75 100 125Temperature (°C)FIGURE 2-2:(V DD = 5.0V).INL Error vs. Input VoltageFIGURE 2-5:Temperature.Maximum INL Error vs.INL (ppm)1086420-2-4-6-8-10+125 C+85 C+25 C-40 C-5 -4 -3 -2 -1 0 1 2 3 4 5V IN (V)Output Noise (µV RMS )10987MCP35536543MCP3550/1210-2.5 -1.5 -0.5 0.5 1.5 2.5V IN (Volts)FIGURE 2-3: INL Error vs. Input Voltage(V DD = 5.0V, V REF = 5V).FIGURE 2-6: Output Noise vs. InputVoltage (V DD = 2.7V).© 2009 Microchip Technology Inc.
