HD49334AF/AHF
CDS/PGA & 10-bit A/D Converter
Description
The HD49334AF/AHF is a CMOS IC that provides CDS-PGA analog processing (CDS/PGA) suitable for CCD camera
digital signal processing systems together with a 10-bit A/D converter in a single chip.
Functions
• Correlated double sampling
• PGA
• Offset compensation
• Serial interface control
• 10-bit ADC
• Operates using only the 3 V voltage
• Corresponds to switching mode of power dissipation and operating frequency
• ADC direct input mode
• QFP 48-pin package
Features
• Suppresses low-frequency noise output from CCD by the S/H type correlated double sampling.
• The S/H response frequency characteristics for the reference level can be adjusted using values of external parts and
• High sensitivity is achieved due to the high S/N ratio and a wide coverage provided by a PG amplifier.
• Feedback is used to compensate and reduce the DC offsets including the output DC offset due to PGA gain change
• PGA, standby mode, etc., is achieved via a serial interface.
• High precision is provided by a 10-bit-resolution A/D converter.
