  • RE: DAC8718: LDAC delay issue and slew rate issue

    Resolved
    Hi Tristan, I checked with our design team and here is clarification:- " DAC8718/28 have slew boost. If you look closely you can see two different slopes on both rise and fall times. From V0 to V1 positive slew boost is ON and slope is faster after…

  • DAC8718: Dual-Supply Configuration Detection

    Part Number: DAC8718 Hello, I am trying to use the DAC8718SPAG in a dual-supply configuration (+5V AVdd, -5V AVss, +2.5V REF, +3.3V IOVdd ). I also have RSTSEL pin tied to IOVdd and USB/BTC pin tied to ground. My understanding is that the DAC should…
