The device uses an internal charge storage principle where the largest bit-currents are repeatedly generated by a single current reference source, ensuring accuracy insensitive to ageing and temperature variations.
The device is compatible with most current Japanese input formats including time multiplexed, two's complement, and TTL.
No, it does not have zero-crossing distortion due to an implemented symmetrical offset decoding method.
