REV. 1.0.1
3-CHANNEL 16-BIT LINEAR CCD/CIS SENSOR SIGNAL PROCESSOR
GENERAL DESCRIPTION
The XRD9818 is a fully integrated, high-performance analog signal processor/digitizer specifically designed for use in 3-channel/2-channel/1-channel CCD/CIS document imaging applications. Each channel of the XRD9818 includes a Correlated Double Sampler (CDS), Offset adjustment, Programmable Gain Amplifier (PGA). After the gain and offset adjustments the analog inputs are sequentially sampled and digitized by a 16-bit A/D converter. The digital output data is available in 8 or 4-bit wide multiplexed format. The analog front-end can be configured for use in CCD or CIS data acquisition applications.
