AK9813A Datasheet, PDF (12/24 Pages) Asahi Kasei Microsystems – 12ch 8bit D/A Converter with EEPROM

ASAHI KASEI
4.ALL CALL mode : The outputs of the all D/As are set by the data in the internal EEPROM.
[AK9813A]
• _{The D/A outputs are set from AO1 to AO12 in order.}
5.WRITE mode:The digital input data for D/A converter is written into the internal EEPROM.
(NOTE)
∗ In case that AK9813A devices are connected in cascade, when a AK9813A device is under programming
cycle, the AK9813A device under programming cycle can not transfer the data to the other AK9813A device
and some AK9813A devices can not be operated by the common CS signal at the same time.
∗ While programming cycle, the CS/LD pin should be "L".
∗ When the Ready/Busy signal from the DO pin is verified, the CS pin should be changed from "H" to "L" and
kept at "L". If the CS pin is kept at "H", the Ready/Busy signal does not output correctly.
