CT22501

8b-200MSps SubRange Flash ADC

CT22501 is aa dualstage subranging 8bits ADC which is able to operate at 200MSps.

The conversion is thus carried out in 2 stages. The 4 most significant bits (MSBs) results from theoperation of a Coarse Flash ADC. Its outputs are feed to a DAC in order togenerate the inputs for the Fine Flash ADC (FADC) depending both on the input signal to be converted and on the resultsof the first part of the conversion.

The flash ADCs are implemented using dynamic latched comparators, in order to minimize static/DC powerdissipation.  In order to improve accuracy, self calibration is employed. Conversion takes 2 clock cycles.
