摘　　要：AK9813B是一款高速的12通道数模转换器(DAC),主要用于高速高精度要求的电路中,如工业设备、医疗仪器、设备的性能测试、传感器外围电路设计等领域。文中介绍了AK9813B的性能特点、内部结构及引脚排列,给出了AK9813B和单片机连接的原理图及部分程序。The AK9813B includes 12 channels,8 bit 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. The paper introduces the performance,internal structure and pin descriptions of AK9813B, and offer a figure showing a parallel interface between the AK9813B and 8051 mieroeontroller.
