• AD5450 output voltage drop

    Hi,

    I am using AD5450 DAC in one of my projects. I am facing a problem of output voltage drop near  Vref voltage. 

    I am using AD5450 in Bipolar operation mode. The output voltage follows the equation given in Page 17 of the datasheet but the output voltage…

  • AD5450 How to decide R3 resistance constant?

    Hi, all

    Please let me know how to decide R3 resistance constant when Gain is changed.(I refer to figure 45).

    I would like to use bipolar mode and fixed reference.

    Thanks.

  • For the AD5450, does the device care what the clock is doing when the frame line is high?

  • RE: 請問AD7522 有替代的產品?

    两种方式, 1. 虽然这款芯片停产了,但是通过罗彻斯特可以购买,Rochester Electronics 是ADI公司唯一授权的停产产品代理商

    2. 这款芯片很老,可以购买类似的电流输出乘法DAC, 如AD5450/51/52/53/54

  • RE: DAC选型失败,求推荐一个DAC能产生一个50KHZ的正弦波

    您好。DAC更新速度会受到建立时间,和通讯速度,以及其他一些时序要求的影响。

    对于您的应用可以参考使用DDS产生正弦信号,可以参考AD9837。希望使用DAC的话,可以参考AD5512A,AD5552

    I or V out可以参考AD5450,是电流输出的DAC,在Voltage-Switching Mode连接时可以做电压输出

    unbuffered vout和voltage out输出阻抗不同

  • serial interface and input shift register in AD5452

    In page 5 of AD5450/AD5451/AD5452/AD5453 data sheet, Timing Diagramis shown and looks like data is loaded into input shift register in  MSB first manner.

    in the serial interface example in page 21-22, looks like data is loaded in LSB first manner and when…

  • RE: AD9674 TGC Gain input driver

    Hi Gsing,

    With the negative power supply, the circuit is easy, and the ADA4938 is the right part. Using the circuits in the CN0181 and ADA4938 is ok for your design, but I do not think the ADA8657 is good candidate due to bigger noise and small GBP.…
