Revision B, 08.09.02
In Op. Mode 1 (internal references) with VREF = 1 V at 20 MHz clock frequency.
In Op. Mode 4 (external references) with VREF = 1 V at 20 MHz clock frequency.
After 10 µs power down.
The digital output codes of the ADC are not valid during the first few clock cycles after a power up.
