Complete 14-Bit, 56 MSPS

Imaging Signal Processor

AD9941

FEATURES

GENERAL DESCRIPTION

Differential sensor input with 1 V p-p input range

0 dB/6 dB variable gain amplifier (VGA)

Low noise optical black clamp circuit

14-bit, 56 MSPS analog-to-digital converter (ADC)

No missing codes guaranteed

3-wire serial digital interface

3 V single-supply operation

Low power CMOS: 145 mW @ 3.0 V, 56 MHz

48-lead LQFP package

The AD9941 is a complete analog signal processor for imaging

applications that do not require correlated double sampling

(CDS). It is also suitable for processing the output signal from

the AD9940 CDS front end product. It features a 56 MHz, single-

channel architecture designed to sample and condition the output

of CMOS imagers and CCD arrays already containing on-chip

CDS. The AD9941 signal chain consists of a differential input

sample-and-hold amplifier (SHA), a digitally controlled variable

gain amplifier (VGA), a black level clamp, and a 14-bit ADC.

The internal registers are programmed through a 3-wire serial

digital interface.

APPLICATIONS

Digital still cameras using CMOS imagers

Professional HDTV camcorders

Professional/high-end digital cameras

Broadcast cameras

The AD9941 operates from a single 3 V supply, typically

dissipates 145 mW, and is packaged in a 48-lead LQFP.
