    Question:

    The datasheet of CY9A110K series “English version”, for Section 15. Major Changes, states that the typical value of Integral Nonlinearity, Differential Nonlinearity, Zero Transition Voltage, and Full-scale Transition Voltage was added for Section 12.5 12-bit A/D Converter.

     

    The extract from Section 15. Major Changes in CY9A110K Series Datasheet

     

     

    Answer:

    There are no typical values of Integral Nonlinearity, Differential Nonlinearity, Zero Transition Voltage, and Full-scale Transition Voltage in the corresponding Section 12.5 12-bit A/D Converter of CY6A110K Series Datasheet “English version”.

     

     

    However, the “Japanese version” of CY9A110K series showes the updated parameters.

     

     

    Where, “積分直線性誤差” is “Integral nonlinearity”, “微分直線性誤” is “Differential nonlinearity”, “ゼロトランジション ” is “Zero transition voltage”, and “フルスケール トランジション電” is “Full-scale transition voltage”.

     

    As the conclusion, the typical value of these parameters are:

     

    • Integral Nonlinearity = ± 1.7 [LSB]
    • Differential Nonlinearity = ± 1.5 [LSB]
    • Zero Transition Voltage = ± 8 [mV]
    • Full-scale Transition Voltage = AVRH ± 15 [mV]
