Specifications for DC Offset
An A/D converter usually does not produce digital zero output from analog zero input because the operational
amplifier inside has an offset. The MN6460A, however, has circuitry for correcting this. The shipping inspection
enables this offset correction circuit and confirms that the DC offset is within the lower four bits.
