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.

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.
