  • TLC7226: DAC IC is failing

    Part Number: TLC7226 Hi, Presently using TLC 7226CN DAC IC. I want to know in DAC chip AGND & DGND must be separate in layout? What if both are shorted. This IC is frequently failing after 4-5 days of operation,no heating found,operated under recommended…

  • TLC7226: The four ouputs change from operating voltage to 0V without any control.

    TI Thinks Resolved
    Part Number: TLC7226 The TLC7226C outputs connect to max301 directly. Sometimes the four outputs change from operating voltage to 0V . I can confirm that Mcu do not control it. What happened will the output reset to 0V?
