  • 6 dB to 42 dB, 10-bit variable gain amplifier (VGA)
  • Low noise optical black clamp circuit
  • Preblanking function
  • 12-bit, 45 MHz ADC
  • No missing codes guaranteed

  • 3 V single-supply operation
  • Space-saving, 32-lead, 5 mm × 5 mm LFCSP

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.
