Description
The HD49323AF-01 is a CMOS IC that provides CCD-AGC analog processing (CDS/AGC) suitable for CCD camera digital signal processing systems together with a 10-bit A/D converter in a single chip.

Functions
• Correlated Double Sampling
• AGC
• Sample hold
• Offset compensation
• Serial interface control
• 10-bit ADC
• 3 V single operation (2.7 V to 3.6 V)
• Power dissipation: 198 mW (Typ)
• Maximum frequency: 20 MHz (Min)

FEATUREs
• Good suppression of CCD output low-frequency noise is achieved through the use of S/H type correlated double sampling.
• A high S/N ratio is achieved through the use of a AGC type amplifier, and high sensitivity is provided by a wide cover range.
• An auto offset circuit provides compensation of output DC offset voltage fluctuations due to variations in AGC amplifier gain.
• AGC, standby mode, offset control, etc., is possible via a serial interface.
• High precision is provided by a 10-bit-resolution A/D converter.
• Version of Hitachi’s previous-generation HD49322BF with improved functions and performance, including in particular an approximately 3.0 dB improvement in S/N.
