HD49330AF/AHF
CDS/PGA & 12-bit A/D Converter
REJ03F0102-0100Z (Previous: ADE-207-344) Rev.1.0 Apr.05.2004

Description
The HD49330AF/AHF 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.

Functions
Correlated double sampling PGA Offset compensation Serial interface control 12-bit ADC Operates using only the 3 V voltage Corresponds to switching mode of power dissipation and operating frequency Power dissipation: 150 mW (Typ), maximum frequency: 36 MHz Power dissipation: 80 mW (Typ), maximum frequency: 20 MHz ADC direct input mode Y-IN 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 registers. 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 and the CCD offset in the CDS (correlated double sampling) amplifier input. PGA, standby mode, etc., is achieved via a serial interface. High precision is provided by a 12-bit-resolution A/D converter.
