CCD Signal Processor
ADDI7100
GENERAL DESCRIPTION
The ADDI7100 is a complete analog signal processor for charge-
coupled device (CCD) applications. It features a 45 MHz,
single-channel architecture designed to sample and condition
the outputs of interlaced and progressive scan area CCD arrays.
The signal chain for the ADDI7100 consists of a correlated double
sampler (CDS), a digitally controlled variable gain amplifier
(VGA), a black level clamp, and a 12-bit ADC.
The internal registers are programmed through a 3-wire serial
digital interface. Programmable features include gain adjustment,
black level adjustment, input clock polarity, and power-down
modes. The ADDI7100 operates from a single 3 V power supply,
typically dissipates 125 mW, and is packaged in a space-saving,
32-lead LFCSP.
