General 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 Power dissipation: 120 mW (Typ), maximum frequency: 36 MHz (HD49334AHF) Power dissipation: 60 mW (Typ), maximum frequency: 25 MHz (HD49334AF) • ADC direct input mode • QFP 48-pin package

Overview

HD49334AF/AHF CDS/PGA & 10-bit A/D Converter REJ03F0105-0100Z Rev.1.

Key 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.
