DAC7802: DAC7802 logical thresholds

Part Number: DAC7802

Dear Texas Instruments,

i would like to use the DAC7802 or DAC7800 due to its good properties with an FPGA that only supports 3.3V. Unfortunately, I was not able to find the threshold in the data sheet at which the DAC does recognize a logical 1 or a logical 0. Can the DAC also work with 3.3 V on the logic signals?

Best Regards

Molaris

  • Hi Uzamis,

    The DAC780x requires a 4.5V to 5.5V VDD supply, but the logic levels will work with 3.3V logic.  See the VIH and VIL levels in the datasheet:

    Thanks,

    Paul
