Input/Output T ransfer Func tion
CCD Input
Figure 11 shows the MAX1101 transfer function for
CCDIN. Coding is binary, with a -4LSB offset added to
ensure that offsets within the MAX1101, which can be
positive or negative, do not cause the ADC to be out of
range. Full-scale input range at CCDIN is:
(V
REF+
- V
REF-
) / G
PGA
where G
PGA
is the gain of the programmable gain
amplifier.
Analog Inputs (AIN_)
The transfer function for auxiliary inputs is shown in
Figure 11. Again, coding is binary and full-scale range
is V
REF-
to V
REF+
. An offset has not been added to
these channels; however, code transitions occur at the
1/2LSB point, as shown in Figure 12.
Implementing Correlated
Double S ampling (CDS ) or
Blac k-Level Compensation
The CLAMP circuit in the MAX1101 can be used to either
accomplish CDS or to compensate for the CCD black
level. To accomplish CDS, CLAMP is activated once per
CCD (OUT)
