• RE: ADN8831 TEC controller - 24 Voltage Application?

    Hi Andy,

    I am going to use ADN8831 to our optic system. Can I get spice model of ADN8831?

    I downloaded ADI_All_spice_models, but I couldn't find ADN8831.

    Thanks

    David

  • ADN8831 and operate DVDD with < 3v

    The datasheet specifies that minimal PVDD as 3V.

    Can PVDD operate < 2V

     

    Impossible. ADN8831 has one feature called Undervoltage Lockout (UVLO) = typ.
    2.2V.

    ADN8831 won’t work if any external supply rail applied to the ADN8831…
  • ADN8831 problem

    Hello to all


    I have some problem about adn8831.We use adn8831 to control a TEC of pump laser. But PWM waveform does not appear in the pin 19 and pin 21.Also the Votage on the pin14 is 0.1V. It's seems that ADN8831 in Standby mode.

  • ADN8831: How to drive a 12V TEC?

    Can we use ADN8831 to drive a 12V TEC.

     

    The ADN8831 only supports up to 5.5V and is not compatible with 12V TEC module.

    您好:

          我是ADN8831的用户,最近在调试时发现以下问题,亟待您的技术支持:

        

          1.在控制TEC温度中,稳定时间有点长,调整P参数后,变得不稳定;

          2.制热状态时,OUT1输出能够和温度设定电压跟随,但在制冷模式时,OUT1和温度设定电压差很大,长时间不能锁定

          3.在上述2描述的状态中,TEC的温度确是能够正常体现的?

         

          电路设计,参数配置,我们参考的ADN8831评估板(AN-695)

          亟待您的解决方案,望尽快回复!
