    GENERAL DESCRIPTION
    The XRD9814B/9816B is a fully integrated, high-per-
    formance analog signal processor/digitizer specifi-
    cally designed for use in 3-channel linear Charge
    Coupled Device (CCD) and Contact Image Sensitive
    (CIS) imaging applications.
    Each channel of the XRD9814B/9816B 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/
    16-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/9816B suitable for use in CCD,
    CIS and other data acquisition applications.
     14-Bit or 8-Bit (Nibble) Parallel Data Output
    (XRD9814B)
     16-Bit or 8-Bit (Nibble) Parallel Data Output
    (XRD9816B)
     5V Operation and 3V I/O Compatibility
     Low Power CMOS: 500mW @ 5V
    The CDS mode of operation supports both line and
    pixel-clamp modes and can be used to achieve signifi-
    cant reduction in system 1/f noise and CCD reset
    clock feed-through. In S/H mode the internal DC-
    restore 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 adjust-
    ment 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.
