GENERAL DESCRIPTION
The XRD9827 is a complete linear CIS or CCD sensor
signal processor on a single monolithic chip. The
XRD9827 includes a high speed 12-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 XRD9827. 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 appli-
cations that do not require CDS function, such as low
cost data acquisition.
