com 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 (HD49340HNP) Power dissipation: 60 mW (Typ), maximum frequency: 25 MHz (HD49340NP) • ADC direct input mode • QFN 36-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 10-bit-resolution A/D converter.
