Internal Reference Positive Output. Requires a low ESR (under 1.5 Ω) ceramic bypass
capacitor of 2.2 μF to analog ground. (O)
ADCREFP 56 P5 P5
NOTE: Use the ADC Clock rate to derive the ESR specification from the capacitor data
sheet that is used in the system.
Internal Reference Medium Output. Requires a low ESR (under 1.5 Ω) ceramic bypass
capacitor of 2.2 μF to analog ground. (O)
ADCREFM 55 N5 P4
NOTE: Use the ADC Clock rate to derive the ESR specification from the capacitor data
sheet that is used in the system.
