PRODUCT DESCRIPTION
The AD9822 is a complete analog signal processor for CCD
imaging applications. It features a 3-channel architecture
designed to sample and condition the outputs of trilinear
color CCD arrays. Each channel consists of an input clamp,
Correlated Double Sampler (CDS), offset DAC and Pro-
grammable 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 sensors,
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
registers are programmed through a 3-wire serial interface, and
provide adjustment of the gain, offset, and operating mode.
The AD9822 operates from a single 5 V power supply, typically
consumes 385 mW of power, and is packaged in a 28-lead SOIC
or SSOP.
