Part Number: DAC80504
We are planning to use DAC80504 in our application. we would want to give reference of 5V to REF pin. Our VDD is +5V. Datasheet says Reference input range can be equal to VDD if REFDIV is enabled. If we enable REFDIV(i.e, REFDIV=1), and Gain = 1, VOUT can be in range of 0-Vref. Does that mean Vout is 0-5V ?
As per our understanding we can give 5V external reference , then we will set REFDIV=1, GAIN=1 to get Output voltage range 0 to 5V. Please confirm.
Awaiting for the quick response.
Thank you for your query. The output voltage range to the VDD supply is related through the output voltage headroom as specified on page 8 of the datasheet. It is 4 mV typical for an unloaded condition. If you are using a 5V reference, we would recommend using 5.5V as VDD to get the entire output range.
Hope that answers your question.
