GENERAL DESCRIPTION

The XRD9826 is a complete linear CIS or CCD sensor

signal processor on a single monolithic chip. The

XRD9826 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 XRD9826. 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 configura-

tion. 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.
