  • ADuC847: Noise perfomance

    Q 

    We are using your ADuC847 microconverter to interface to a strain-gauge load
    cell for a weighing application.
    The load cell output is 0 - 10mV and is connected to Ain1+ and Ain-.
    The ADC is configured for a unipolar, fully-differential, 0 - 20mV…

  • ADuC847 noise

    Hello, 

    I'm currently working with an ADuC847 processor to read signals from a load cell, the signals are in the range of 0mV to 10mV. The problem is that i'm facing way too much noise on the reading, i've tried a lot of things, enable and disable CHOP…

  • ADuC847: Crystal start up

    Q 

    I'm using ADuC836 with 85SMX watch crystal and all is working fine. With the
    same crystal and ADuC848/847 samples, the oscillation don't start. I try 3
    samples but nothing. why? could oscillator section be different from 836 to
    847/848…

  • Recommended programming socket for ADuC847

    Q 

    We are using more than 10 000 pcs/year ADuC847 56-Lead LFCSP. For our service
    center we need to have pre-programmed processors, and currently our service
    engineers have to solder them. Could you recommend a test/programming socket,
    where we can…

  • ADUC847 External reference voltage range

    Q 

    Based on the information on datasheet it's not clear to us that would it be
    safe to use 5V reference with 5V / 3.3V power?

     

    A 

    The REFin + to REFin- range is 1v to AVdd. So the external reference can not
    exceed AVdd.

  • ADuC847: Using aspire in debug run mode

    Q 

    I am using the QuickStart kit for downloading and debugging. In debug step by
    step mode the Aspire 1.06 software tool works fine.
    However when goes in run mode and then I  press the Stop/Pause buttons the
    Aspire warns with the message "Failed to…
