HD49338F/HF
CDS/PGA & 12-bit A/D Converter
Description
The HD49338F/HF 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
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
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
PGA, standby mode, etc., is achieved via a serial interface.
High precision is provided by a 12-bit-resolution A/D converter.
