ADC bits required

Minimum noise after CDS and other corrections

Measured fixed pattern noise for APS 3 or 1, ask Fabrice

Max Signal

Leakage current

Frame readout time

Number of frames read before reset

Total accumulated leakage charge

Dynamic range that ADC must cover

number of ADC bits to cover dynamic range

(just checking)

number of adc bits for a given number of frames without reset.

Conceivably a discriminator would be set at 2.5 times noise so min ADC count could be 2 times noise and therefore might get by with one bit less in the ADC
