• 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.
