• Zero-Scale Error of DAC

    I find some DACs from ADI specified their Zero-Scale Error, such as AD5761, but some not, such as AD5543. I've noticed AD5761 is a voltage output DAC, but AD5543 is a current ouput DAC. So I think the external OP may play important role at this aspect…

  • 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,

    Ivan

    Hi,

    Unfortunately we are not able to comment about the competitor's products. If you are looking for precision DACs, you can use ADI's Parametric Search for Precision DACs by clicking to this link. You may want to take a look at these particular…

  • RE: AD5546或者其他电流输出DAC输出电流精度问题

    专家回复:

    AD5546不是电流源输出型的DAC。他的电流输出只有在Iout接到0V的时候才是有效的。因此必须外接放大器进行I/V转换。他的电流输出误差有20%,但是通过内部的反馈电阻的匹配精度,再搭配放大器使用的时候,转换出来的电压信号会有16位的精度。若您想实现高精度可编程电流,需要自己做出额外V/I转换的电路设计。AD5543的数据手册中的“可编程电流源”章节给出了一些最基本的建议。AD5543是和AD5546很类似的DAC。

  • RE: Need help picking Multiplying DAC, 60mV full scale output, 1uV resolution, input 5-10vDC, 2-quadrant

    Hi Lloyd,

    You may want to look at AD5543 for your application. We are also thinking of the same thing about scaling down the input first to maximize the DACs resolution.

    If you have a schematic that we could take a look at, we could provide more suggestions…

  • RE: Fast Settling 16-Bit DACs

    Hi DanTech,

    The AD5543 requires an op amp on the output for the I-to-V conversion, the voltage-switching mode is not an option here.

    Might be interesting to consider the AD5760, 16-bit ultra stable voltage output DAC. If settling time is key in your…

  • RE: ADI ADC + TI DAC ... will be a problem

    Hi jk,

    Since the Analog Devices part is functioning normally and your problem is related to the TI DAC, unfortunately we’re not able to provide support for this issue.  I would suggest contacting TI support to try to resolve it.  If you continue to have…

  • 100Hz to 1.25MHz signal generation with AD9952

    Hi

    we are in prototyping and test stage with an larger design hat involves over 30 ADI IC's (over 20 different ones!) - one part of the design is sinus signal generation with single frequency range span of 100Hz to 1.25MHz (output +-10V single ended…
