• AD5544: Bandwidth charts for code different than FFFF

    Dear,

    I need data about AC behavior of AD5544 but in the datasheet, picture 21 shows:

    * only data for AD5554 (14-bit) but I need that data for AD5544 (16-bit)

    * only for code 0xFFFF, but I'm interested in data for lower codes to be able to compare…

  • AD5544 Channel A Power-On-Reset Value is Incorrect

    Hi,

    I have two AD5544 DACs on my board, each with an independent SPI interface going to it. The board is configured such that all channels should start out at zero scale. When the board is powered up, I find that channel A starts up at full scale, whereas…

  • AD5544的18bit数据传输的问题

    AD5544的18位数据由2bit地址位和16位数据位组成,采用标准SPI的时候一次传输8位数据该如何传输呢?是从17-0位放置数据还是23-6位放置数据呢。datasheet上说最后18位被保留不知道什么意思

  • query regarding Electric characteristics of AD5544 current output DAC

    Hi,

    1. In the data sheet of AD5544 it was mentioned that the static performance parameters like INL, DNL, Full scale gain error are the values correspond to closed loop system using an external precision I-V converter amplifier (OP177).Would like to know…

  • AD5544数据手册貌似有错误   求大神给出意见!!!

    在使用AD5544过程中,按照AD5544数据手册(Rev.F|Page 19 of 28)里边的应用信息,如图,但经过实验无法实现四象限乘法应用功能:放大器A2的接法有错误,应该把A2的同相输入端接RFBX经过5K电阻的输出(也就是A1的输出接5K电阻然后街道A2同相输入端),而不是接地。


    求大神给出意见!!!

     

     

     

  • 用AD5544实现数模转换,UG-285评估板怎么使用

    刚接触这一块,要用AD5544实现数模转换功能,有UG-285评估板资料,想问各位大神评估板原理图该怎么简化,SDP板一定要用上吗?
    望大家赐教!

  • How to compare settling times of DACs

    I am unsure how to compare the settling times of the AD5544 and the AD5686, due to the different way in which they were measured.

    The AD5544 goes from 0 to full scale then back to zero and has a settling time of 0.9us to plus/minus 0.1% full scale. The…

  • 用DAC实现uA级电流输出的控制

    我想做个用DAC控制的电流输出的电流精确控制电路,输出电流在微安级别,请问用什么芯片好。我看过两款芯片AD5544和AD5554,但是感觉不是我想要的。求推荐相关资料!!!

  • RE: Looking for Serial 16 bit Multiplying DAC, AC Reference

    Hi, 

    You may want to check out AD5544 and AD5543 as they are 16-bit MDACs with serial interface, though they just don't have integrated 4-quadrant resistors. 

    Cheers,
