  • AD7792: Communication problems

    Q 

    I have the problem that the AD7792 doesn't talk to me over SPI. I try to read
    out the ID register as a start. The /CS is correctly low, the read-command is
    transmitted correctly and there are clock pulses for the response but no data
    is coming…

  • AD7792: On-Chip temperature

    Q 

    We use AD7792 for our RTD measurement system. Page 4 (REV A datashee) show
    characteristics for "TEMPERATURE SENSOR". Could you please explain me what is
    this about ? Does it means that the chip has got an embedded temperature sensor

  • AD7792: Single vs. Continuous Conversion Time

    Q 

    Do you have any data on Single vs. Continuous Conversion Time?

     

    A 

    The conversion time depends on if you are using single conversion mode or
    continuous conversion mode. For continuous conversion the first conversion is
    available after a period of…

  • Long term drift of the AD7792 Reference

    Q 

    Can you provide any information on the Long term drift of the AD7792 Reference?

     

    A 

    A typical long term drift figure would be 50ppm/1000hrs for the reference on
    the AD7792.

  • AD7792: AVDD monitor and temperature sensor channel

    Q 

    We intend to use AD7792 in a new product and I am implementing the software
    that communicates with the AD7792. The only documentation I can find on your
    web site is the data sheet. I can not find all the information I need so I
    would like to know…

  • AD7792: Using multiple device on the serial bus

    Q 

    I am currently using the AD7792 converter on a board together with some other
    devices on the common SPI bus, however when designing I didn't realize that the
    AD7792 will pull it's DOUT pin low whenever a conversion is complete. Wont
    there…

  • AD7792 readback is wrong

    i use ad7792 with pt100。

    the voltage of pt100 is 0.107V，

    7792 setting is  REF=3.3v   1/16, ( 0.20625v ) IOUT=1mA，

    But it“s readback data is always  half of 65536，

    It's wrong.I wonder know how.

    Best regards.
