GENERAL DESCRIPTION
The XRD9825 is a complete linear CIS or CCD sensor
signal processor on a single monolithic chip. The
XRD9825 includes a high speed 16-bit resolution ADC,
a 6-bit Programmable Gain Amplifier with gain adjust-
ment of 1 to 10, and 8-bit programmable input referred
offset calibration range of 800mV.
In the CCD configuration the input signal is AC coupled
with an external capacitor. An internal clamp sets the
black level. In the CIS configuration, the clamp switch
can be disabled and the CIS output signal is DC
coupled from the CIS sensor to the XRD9825. The CIS
signal is level shifted to VRB in order to use the full
range of the ADC. In the CIS configuration the input can
also be AC coupled similar to the CCD configuration.
This enables CIS signals with large black levels to be
internally clamped to a DC reference equal to the black
level. The DC reference is internally subtracted from
the input signal.
The CIS configuration can also be used in other
applications that do not require CDS function, such as
low cost data acquisition.
