• AD7865: Multiple CONVST

    Is it possible to restart the con version with two consecutive /convst signals
    in direct requence (double function of signal necessary) ? The second pulse
    will follow the first directly (100ns pulse width )

     

    A conversion is triggered off the…

  • AD7865 supply voltage

    Hi,

    The AD7865 is specified to operate from an AVDD supply of 5V +/-5%. What would happen to the sampled data if it is operated outside of these 5% limits?

    In a legacy design, the AVDD pins is connected via a simple RC low pass filter, R is 10 ohms…

  • DAC AD7836 and ADC AD7865

    Dear Madam / Sir,

    Kindly clarify the following points:

    1. AD7836 requires 5-V for logic circuit and +/- 15-V and Vref+ and Vref- for the analog section.

    Is there any powering sequence for these voltages or can we power up simultaneously.

    Of course…

  • AD7891AS and AD7865BS-1 have been stressed to +225C (10second) IR soldering. Will this destroy the components?

  • AD7865AS-2 and ad7865ASZ-2差异?

      在设计中采用AD7865 4通道ADC采集数据,由于采购问题,第一次采购的了AD7865AS-2,

    第二次采购回来的是 AD7865asz-2. 通过数据手册查看到二者没有区别,但是在使用中对于同样的

    情况采集回来的数据有大概4倍的差异,请问是正常的,还是有什么地方需要注意的?

    以下数据为对某4个通道采样后的量化数据(二者工作的状态相同,工作电压和硬件电路相同):
