| Analog Source Resistance | 12 bit mode f ADCK = 40MHz ADLSMP=0,
ADSTS=10, ADHSC=1 | RAS | — | — | 1 | kohms | Tsamp=150ns |
RAS depends on Sample Time Setting (ADLSMP, ADSTS) and ADC Power Mode (ADHSC, ADLPC). See charts for Minimum Sample Time vs RAS.
Where can I find these "charts" with RAS vs. minimum sample time? What is the largest RAS value which the ADC can handle (at the lowest possible sampling time)?
