• The out of AD7989-5 is wrong

    The power of ad7989-5 must be 2.5V? i use 3.3V, and then i use single mode directly ,the result is that if ain+ is under 2.0v, the adc out is wrong,  how to solve the problem on pcb board?, 3.3V or  single mode?

  • AD7989-5 power consumption

    Hi,

    On the AD7989-5 data sheet it is mentioned that the total power dissipation  is 3.5 mW at 500 kSPS. 

    On the web page http://www.analog.com/en/products/analog-to-digital-converters/ad7989-5.html#product-overview it is mentioned 3.5 μW. 

    I assume that…

  • AD7989-5的使用方式问题

    您好,我想请问下AD7989-5是否支持我下面的单端输入方式,我看着这个芯片应用一般是差分输入,如果使用单端到这个ADC芯片,推荐的是使用ADA494-1单端转差分的芯片,但是芯片的首页也表明了引脚兼容如下图所示,所以我疑惑是否我运放出来的单端输出可以直接接到这个AD?如图的接法,是否会有什么问题?

    AD7989-5的产品说明书中关于芯片SINAD随信号频率变化图见下图

    从图中看,在测试这款芯片时,100KHz时信号精度至少高于90dB

    请问在测试这款新品的时候,输入的模拟信号是使用什么仪器产生的?如果是APx555,能产生250KHz的模拟信号吗?

  • LT1964_difference between the LT1964ES5-5#PBF and LT1964IS5-5#PBF

    Dear team,

    Could I know the difference between LT1964ES5-5#PBF and LT1964IS5-5#PBF?

    It seems that these parts are same parts(performance, quantity)

    The price difference is checked, but I don't know why.

    Dear

    We are going to use LT8609AEDDM#TRPBF for our products to launch the market now, however we cannot get yor chips now seriously, so might be stopped ship our product.

    Well maybe it is irregal idea but let me know, can we use  the LT8609AHDDM-5#TRPB…
