PRODUCT DESCRIPTION
The AD9814 is a complete analog signal processor for CCD
imaging applications. It features a 3-channel architecture de-
signed to sample and condition the outputs of trilinear color
CCD arrays. Each channel consists of an input clamp, Corre-
lated Double Sampler (CDS), offset DAC and Programmable
Gain Amplifier (PGA), multiplexed to a high performance 14-
bit A/D converter.
The CDS amplifiers may be disabled for use with sensors such
as Contact Image Sensors (CIS) and CMOS active pixel sen-
sors, which do not require CDS.
The 14-bit digital output is multiplexed into an 8-bit output
word that is accessed using two read cycles. The internal regis-
ters are programmed through a 3-wire serial interface, and pro-
vide adjustment of the gain, offset, and operating mode.
The AD9814 operates from a single +5 V power supply, typi-
cally consumes 330 mW of power, and is packaged in a 28-lead
SOIC.
