GENERAL DESCRIPTION

The XRD98L23 is a complete linear CIS or CCD sensor

signal processor on a single monolithic chip. The

XRD98L23 includes a high speed 8-bit resolution ADC,

a 6-bit Programmable Gain Amplifier with gain adjust-

ment of 1 to 10, and a typical 8-bit programmable input

referred offset calibration range of 480mV.

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 XRD98L23. 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.
