Yang,

The F28335 can accept inputs and outputs from 3.3V signals. Its IOs are not 5V tolerant. By putting the supply of the TLV5616 at 3.3V instead of 5V (and adjusting VREF accordingly) you will likely be able to interface the DAC correctly.

Thank you,
Brett

Dear Brett,

Thanks your proposal, but I must make my DAC output range 0 to 5 voltage.

If TLV5616 be at 3.3V,that can't reach my want.

Thank you
