• LTC2470 reading jumps by 15

    I'm using the LTC2470 to read the output of an analog hall effect sensor and it is working fine except that the reading jumps by steps of about 15 numerically as the sensor output changes (I assume 4 bits). Is there some reason why the 4 lowest bits would…

  • AD9914/15 POW word

    Hi

    In the AD9914/15 Profiles mode, can anyone confirm that:

    1. The POW word should be calculated according to equation given on page 19 of datasheet

    2. This equation gives a 14 bit word

    3. This word should be stored in the 14 LSB bits of the 16 bits…

  • AD9914/15 PLL pins

    I have a question about the 9914/15 chips -  if the PLL if not used, can the PLL pins be left floating ?

    Also, is it safe to tie the profile, F0/3 mode pins and everything else that should have a static logic level directly to ground or 3.3 DVDD or resistors…

  • ADuC7026 XMxPAR[15] behavior

    Hi All,

    According to datasheet(revF), setting XMxPAR[15] allows byte write capability without using BHE and BLE for two 8 bit memory sharing the same memory region.

    Now, I have following question about this behavior.

    When set XMxPAR as 0xF0FF and write…
