Asahi Kasei Microdevices AK9813A
The AK9813A includes 12 channel, 8bit D/A converters with on-chip output buffer amps and it is capable to store the input digital data of each DAC by on-chip non-volatile CMOS EEPROM. The AK9813A is optimally designed for various circuit adjustments for consumer and industrial equipments and it is ideally suited for replacing mechanical trimmers. When the CS pin is high level, the DO pin becomes high impedance.| Part No. | AK9813A |

DESCRIPTION
(1) No. 20 DI Pin Name I/O I Function [AK9813A] 17 DO O 19 CLK I 18 CS/LD I Serial Data Input Pin SEL=High : 16bit data input format SEL=Low : 14bit data input format (SEL=High:CS I/F) AK9813A reads out the data with LSB first in the 16bit shift register to DO pin synchronously with falling edge of CLK. In STATUS mode, the DO pin outputs Ready/Busy status. (SEL=Low:LD I/F) AK9813A reads out the data with MSB first in the 14bit shift register to DO pin synchronously with falling edge of CLK.
