  • Aduc7122 Operation Temperature?

    Hi All,

    I am considering to use Aduc7122 device which has 13 ADC and 12 DAC channel. But DAC port number of Analog Production site is shown with 4 Port. Please see below site.

  • I2C interfacing MAX44009 with ADuC7122


    I'm trying to interface MAX44009 with ADuC7122 using I2C protocol. I'm attaching the project code used for reading data from sensor but it is not working.Kindly let me know what need to be done to do single read  as well as burst read. Also…

  • Flash over I2C on ADuC7122


    I'm following instructions in http://www.analog.com/media/en/evaluation-boards-kits/evaluation-board/ADuC7XXXGetStartedGuide.pdf for my EVAL-ADuC7122QSPZ starter kit. On page 23 of the guide for Windows I2C Downloader, it instructs me to use …

  • ADuC7122 UART/I2C co-use

    I am using the ADuC7122 micro in an application where we need 2 I2C busses AND a UART. It appears that the UART shares pins with I2C1. We can effectively control when we TX on the UART to ensure that we do not interfere with I2C operation but, of course…

  • ADuC7122 SPI clock not behaving as expected

    I'm trying to use the SPIDIV register to set the SPICLK frequency on my ADuC7122, and I'm seeing unexpected behavior.

    At SPIDIV = 1, 7, and 63, the clock looks approximately like I'd expect based on the datasheet:




    But at…

  • Aduc7122 getting programmed but not giving output.

    I'm using Aduc7122 micro controller and wanted to test it using sample code provided for DAC.I use Keil software and Ulink2 for programming and loading code respectively. When loaded it showed Programming done,Verify OK, Flash load finished but there…

  • What is the pull-up resistor value on the ADuC7122 GPIO inputs?

    What is the value of the pull-up resistor on the  ADuC7122 GPIO pins?

  • If i use a AVdd of 5V and buffer on(ADuC7122) or external reference (ADuC7023) , then can i use signals with 5V input to ADC pins as well as output of 5V from DAC pins.

    Please refer to page 6 of ADuC7122 and page 7 of ADuC7023. In respective pages it is mentioned Buffer Enabled single-ended mode (ADuC7122) and External Reference input voltage range as 0 to AVdd.

    Please suggest an alternate method to use an input and…
