  • AD420: Accuracy of Vout

    I work on a AD420 based application. I wish to have a current and a voltage
    output with the same device. I made a prototype with your AD420, the current
    output works very well. But with the voltage output, I don't have a good
    linearity…
  • AD420: Output voltage range

    the output voltage range of the ad420 is only 4,90V and not 5V!!
    What?s wrong??

     

    The AD420 is primarily used as a precision current output DAC in 4-20mA loop
    systems delivering a programmed current into a grounded load. In voltage output…

    Offset Adjustment and Gain Adjustment

     

    The gain adjustment range is fairly easy to calculate given other
    information on the data sheet, but the offset adjsut is more difficult
    without the internal schematics.

    Gain adjust: The 5k RSPAN2 resistor…

  • AD420: Maximum output current and maximum current absorption

    1) Which is the maximum output current available in voltage mode (0-5V olutput)
    ?
    2) Which is the maximum current absorption from power supply when I put Vcc =
    +15V

     

    1)The voltage output should be loaded by a high impedance only…

  • AD420一直输出4mA

    AD420一直输出4mA。。。。利用SPI输入,检测DATA IN和DATA OUT均有信号,LATCH也有低电平到高电平的转换,感觉是数据没有写入DAC,检测FAULTDETECT为高电平,CLEAR为低电平。求解答
