Description
The HD49343NP/HNP is a CMOS IC that provides CDS-PGA analog processing (CDS/PGA) suitable for CCD camera digital signal processing systems together with a 12-bit A/D converter in a single chip.

FEATUREs
• Suppresses the CCD reset noise by the correlated double sampling.
• High sensitivity can be achieved by 10 bit gray scale provided by PGA which can be set to –6 to 34 dB.
• PGA gain, S/H frequency response, pulse timing, etc., is achieved via a serial interface.
• High precision is provided by a 12-bit resolution A/D converter.
• Difference encoded gray code can be selected as an A/D output code. It is effective in suppression of solarization (wave pattern). It is patented by Renesas.

Functions
• Correlated double sampling
• PGA
• Serial interface control
• 12-bit ADC
• Operates using only the 3 V, ADC output
• Corresponds to switching mode of power dissipation and operating frequency
