• RE: AD5545, error in data sheet?

    Hi,

    It seems the VIN and Vout pins were interchanged in the figure, we'll include this in the next datasheet revision. Though the rest of the circuit is correct for the four-quadrant multiplying application. 

    And, BTW, another question…

  • AD5545 Dual DAC using shared reference

    Hi,

    I would like to use one reference for both DACs of the AD5545. My question is if it would be suitable to connect both reference pins (VrefA and VrefB) to the output of the reference without using switches in the two lines. Attached is a snippet of…

  • 双通道DA转换器使用(求斑竹解答) AD5545

    AD5545是一款双通道,16位DA转换器,可用作可编程增益放大器。其数据格式由用于区分两个通道的2位地址位A1、A0和本身16位的数据构成的一个18位形式。即2位Address+16位Data。
    现比如我要对A通道进行转换,经过计算得到的数字量D为0xAAAA,按照其数据格式,发送的18位格式的数据应该为01
    1010 1010 1010 1010
    ,AD5545是与MSP430单片机进行通信,现请问,我要怎么样发送数据才能得到正确的结果?请斑竹及ADI的技术工程师解答,谢谢!!!

  • [征文+原创] 电流输出型DA转换器AD5545的原理,应用及编程

    AD5545是一款电流输出型的16位DA转换器,采用5 V单电源供电,具有最高±15

    V的双极性输出能力。数据接口利用串行数据输入(SDI)、时钟(CLK)和芯片选择(/CS)引脚,提供高速、三线式微控制器兼容型输入。

    当用作DA转换时,根据ADI给出的datasheet,推荐连接电路如图2所示

    上述电路图,在本质上相当于一个反相放大器,构成反相放大的两个电阻为Rfb与Iout之间的等效电阻R1,Vref和Iout之间的等效电阻R2。则有Vout=

    通道地址编码

    软件实现:MCU用MSP430F149,DA转换器用上述提及的AD5545,SPI时序用软件模拟的方式实现。电路设计中SPI接口的CS由P1.0控制、CLK由P3.3控制、SDI由P3.1控制。自己认为,在软件设计中,难的是对数据的处理,尤其是2位地址+16位数据构成的18位格式的数据。不过好在,在AD5545的datasheet上下面一段话:
