The XRD9814B is a fully integrated, high-performance analog signal processor/digitizer specifically designed for use in 3-channel linear Charge Coupled Device (CCD) and Contact Image Sensitive (CIS) imaging applications.
Each channel of the XRD9814B includes a Correlated Double Sampler (CDS), Programmable Gain Amplifier (PGA) and channel offset adjustment. After gain and offset adjustment, the analog inputs are sequentially sampled and digitized by an accurate 14-bit A/D converter. The analog front-end can be configured for inverting/non-inverting input, CDS or sample-hold (S/H) mode, or AC/DC coupling, making the XRD9814B suitable for use in CCD, CIS and other data acquisition applications.
The CDS mode of operation supports both line and pixel-clamp modes and can be used to achieve significant reduction in system 1/f noise and CCD reset clock feed-through. In S/H mode the internal DCrestore voltage clamp can be enabled or disabled to support AC-coupled or DC inputs. Sampling mode, 10-bit PGA gain (1024 linear steps), 8-bit fine offset adjustment (256 linear steps), 2-bit gross offset adjustment and input signal polarity are all programmable through a serial interface. PGA gain range is 1 to 10, and channel offset range is -300mV to 300mV for fine adjustment and additional -400mV to +200mV for gross offset adjustment. The A/D Full-Scale Range (FSR) is programmable to 2V or 3V.
