Functions
Correlated double sampling PGA Serial interface control 10-bit ADC Timing generator Operates using only the 3 V voltage Corresponds to switching mode of power dissipation and operating frequency Power dissipation: 220 mW (Typ), maximum frequency: 36 MHz (HD49335HNP) Power dissipation: 150 mW (Typ), maximum frequency: 25 MHz (HD49335NP) ADC direct input mode QFN 64-pin package
Features
Suppresses low-frequency noise, which output from CCD by the 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 dynamic range provided by a PG amplifier. PGA, pulse timing, standby mode, etc., is achieved via a serial interface. High precision is provided by a 10-bit-resolution A/D converter. Difference encoded gray code can be selected as an A/D output code. It is effective in suppression of solarization (wave patt...
