ADuC814
TYPICAL PERFORMANCE CURVES
The typical performance plots presented in this section
illustrate typical performance of the ADuC814 under various
operating conditions. Note that all typical plots in this section
were generated using the ADuC814BRU, i.e., the B-grade part.
Rev. A | Page 13 of 72
Figure 3 and Figure 4 show typical ADC integral nonlinearity
(INL) errors from ADC Code 0 to Code 4095 at 5 V and 3 V
supplies, respectively. The ADC is using its internal reference
(2.5 V) and operating at a sampling rate of 152 kHz. The typical
worst-case errors in both plots are just less than 0.3 LSBs.
