HD49338NP Description
The HD49338NP/HNP 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 pensation 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:...
HD49338NP 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 re
- High sensitivity is achieved due to the high S/N ratio and a wide coverage provided by a PG amplifier
- Feedback is used to pensate and reduce the DC offsets including the output DC offset due to PGA gain change and the CCD
- PGA, standby mode, etc., is achieved via a serial interface
- High precision is provided by a 12-bit-resolution A/D converter
