AK9813B
12ch 8bit D/A Converter with EEPROM
General Description
The AK9813B 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
AK9813B is optimally designed for various circuit adjustments for consumer and industrial
equipments and it is ideally suited for replacing mechanical trimmers.
