    SPECIFICATIONS 3.4.2 A/D conversion enable/disable function The A/D conversion can be enabled or disabled for each channel using this function. By setting A/D conversion disabled for unnecessary channels, the conversion cycle shortens. The conversion cycle is calculated with "Conversion speed (200µs) × Number of conversion-enabled channels".

  • Page 28: Sampling Processing/Average Processing Specification

    3.4.3 Sampling processing/average processing specification The conversion method can be specified from sampling processing/count average/time average/moving average for each channel in AJ65SBT2B-64AD. Specify the conversion method with the lower 8 bit in the CH Average processing setting (RWwm to RWwm+3). Then, in the specified conversion method, set the count average/ time average/moving average with the upper 8 bit.
