DESCRIPTION
AA88043
COMPLETE 10-Bit, 25MHz CCD SIGNAL PROCESSOR
The AA88043 is a complete analog signal processor for CCD application. The signal chain for the AA88043
consists of a correlated double sampler (CDS), a digitally controlled variable gain amplifier (VGA), and a black
level clamp. The AA88043 offers 10-bit ADC resolution. It features a 25 MHz single-channel architecture
designed to sample and conditions the outputs of interlaced and progressive scan area CCD arrays.
FEATURES
•Single Supply Operation: 3.0 V to 3.3 V
•25MSPS correlated double sampler (CDS)
•6dB to 40dB 10-bit variable gain amplifier
•Low noise optical black clamp circuit
•Preblanking function
•10-bit,25MSPS A/D converter
•3-wire serial digital interface
•Space-saving QFN 32L 5 mm × 5 mm package
