GENERAL DESCRIPTION
The XRD9824 is a complete linear CIS or CCD sensor
signal processor on a single monolithic chip. The
XRD9824 includes a high speed 14-bit resolution
ADC, a 6-bit Programmable Gain Amplifier with gain
adjustment 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
XRD9824. 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.
