• ADN8835 Breakdown

    We designed a TEC driver with ADN8835 IC, with the referance designs in the datasheet and demo board documents, it as a digital PID design, with 4.5V Voltage out limit, 2.5A max current out limit settings.
    In the case we apply around 2.5V to the IN2P Dac…

  • ADN8835 Design

    Issue:

    1, There no output when the ADN8835 power-up moment,  and SW shorted to ground.The chance of abnormal problems is high

    2, Please help check the SCH design and confirm the maximum negative voltage withstand of SW PIN

    adn8834是个闭环系统,你的温度设置需要看NTC的温度曲线于你设置的电阻分压的关系,根据这个曲线做Vtempset

  • Low-Powerstate of the ADN8835

    Hello everyone,

    I have a problem with my ADN8835CP-EVALZ-board. From what I can tell it does not power on.

  • ADN8835 温控电路 PID参数调节

    ADN8835 温控电路板,设置好了温度,怎么调节PID补偿网络的电阻电容值,达到合适的数值?或者说怎么用工程整定方法调节PID参数?我把TEC两端电压接到示波器上,怎么看波形,是合适的?波形就是一个高低电平?希望有大佬指教下具体的调节方法?

  • CONFIGURING THE SETPOINT TEMPERATURE with ADN8835CP-EVALZ and ADN8835 BASE BOARD (ADN8834MB-EVALZ)

    Hi,

    I request you to provide me the instructions for the configuring of SETPOINT temperature and the RANGE with the above mentioned boards. Instructions were clear when using AND8831-EVALZ Board but here, no such support.

    May I also know what the equation…

  • ADN8835 voltages of TEMPSET vs temperature - how to calibrate

    It is perhaps an unlearned question.... no, it definitely is an unlearned question......I'm scratching my codie head  :)

    If I use a NTC thermistor of 10k ohms as the sensor - how can I set the temperature in terms of voltage at the TEMPSET input, and…

  • ADN8835 is in the digital PID mode. Heating works 9...12 seconds only.

    Good day,

    ADN8835 is in the digital PID mode. Heating (positive current via load) works 9...12 seconds only. 

    Setup:

    1 Chopper1 is unused.

    2. IN2N and OUT2 are connected together (shorted).

    3. Control voltage from DAC ( 0V) is applied to IN2P. 

    4. VTEC…

  • ADN8835: LTSPICE model

    Hi,

    I'm looking for the LT Spice model for the ADN8835 as I could not find it on the website.

    Can anyone please help me with this ASAP.

    Thanks & Regards,
