PRODUCT DE SCRIPT ION
T he AD9826 is a complete analog signal processor for 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 Programmable Gain Amplifier
(PGA), multiplexed to a high-performance 16-bit A/D converter.
T he AD9826 can operate at speeds greater than 15 MSPS with
reduced performance.
T he CDS amplifiers may be disabled for use with sensors that
do not require CDS, such as Contact Image Sensors (CIS),
CMOS active pixel sensors, and Focal Plane Arrays.
T he 16-bit digital output is multiplexed into an 8-bit output word,
which is accessed using two read cycles. T here is an optional
single byte output mode. T he internal registers are programmed
through a 3-wire serial interface, and provide adjustment of
the gain, offset, and operating mode.
T he AD9826 operates from a single 5 V power supply, typically
consumes 400 mW of power, and is packaged in a 28-lead SSOP.
