Assume that V
Externally, the output range of DAC_raw can be changed by connecting a resistor Rcal to RCAL_DAC_OUT and applying a voltage
V
Special case:
R
Rcal = 0, Vcal = GND ............................. then V
A similar relation holds for the output range of DAC_DARK (RCAL_DAC_DARK can be used to tune the output range of this DAC).
Analog to Digital Converter
The IBIS4-6600 has a two 10-bit flash analog digital converters. The ADCs are electrically separated from the image sensor. The
inputs of the ADC must be tied externally to the outputs of the output amplifiers. One ADC samples the even columns and the other
samples the odd columns. Alternatively, one ADC can also sample all the pixels.

The internal resistance has a value of approximately 577 . Only
277  of this internal resistance is actually used as reference for
the internal ADC. This causes the actual ADC voltage range to
become half of the voltage difference between VHIGH_ADC and
VLOW_ADC. This results in the values listed
external resistors.
