• DAC7760: Latch function

  

  Nam, Dino

  Resolved

  Part Number: DAC7760 Dear team, The latch function DAC7760 seems different from Chip Select function of SPI. If we use single slave, can I use latch pin as a chip select function? For example, latch pin low => 24bit data => latch pin high ?? Please…

• DAC7760: Output true zero voltage and zero current.

  

  Nam, Dino

  Resolved

  Part Number: DAC7760 Dear team, I would like to use 0~10V output and 0 to 20mA or 4 to 20mA. To get true zero output, do we have to use negative supply like general op amp? Thank you.

• DAC7760: SDO pin, push-pull or open drain?

  

  Oba

  Resolved

  Part Number: DAC7760 Hello, I think SDO pin of DAC7760 is push-pull output. But my customer is reporting that it requires an external pull-up. Without the pull-up, it doesn't work. Is SDO open drain? Regards, Oba
