  • Does it use both DACs at the same time? Are the two outputs summed together using series resistors? What are the ranges of the coarse and fine DAC? Could you say current set resolution is 8bit+8bit=16bit?

  • Does it use a 8 bit DAC or a 16 bit PWM to set the load current?

  • DRDY# is not connected to the pull up. You can verify in PCB layout and by measuring the resistance between VCC and DRDY#. Also the overlap in solde mask opening may cause shorts between the pads of the BGA. Ground plane could also be improved. I suggest to re-do PCB layout.

  • Karel, you can place an additional resisitor between these pins if you want to reduce receiver distance range. This is ussually about 90 cm.

No public wish lists :(
