QN908x ADC & DAC Characteristics

Please can you let me know the following characteristics of the ADC and DAC of the QN908x, as I can't seem to find them in the datasheet:

 

  1. ADC worst case ENOB when using full rate 31.25 kSps (14-bit is stated, but from the oversampling ENOB figures in section 14.2, it seems that must be typical)
  2. ADC input voltage range absolute limits when operating in differential mode (I could only see differential limits, not absolute)
  3. DAC output impedance and maximum output current

 

Many thanks,

Andy
