I have use AD5541A ( 16 bit DAC ) for a while and have very good use experience with AD5541A.
now I hope to try their family which is enhance to 18 or 20 bit DAC, that is AD5791.
unfortunately AD5791's positive reference voltage is recommend to operate with 5.0V ~ ( VDD - 2.5V )
but not 2V ~ VDD such as AD5541A ( 16 bit DAC )..
is there have another choice can meet my hope ? thank you!
My hope are list below:
1. VREFp : 2V ~ ( VDD - 2.5V )
2. 18 or 20 bit ( 18 bit may better )
3. un-buffer voltage output
thank you for help!
