   I need a DAC that provides voltage from 0 to 20 V with at least 14 channels, but preferably more. And each channel is independently tunable AD5535 would provide the sufficient uinipolar range but it is overkill for my application.Can you give me some better advice?

    Hi leixue,
    
 
    You can use the AD5535B as the LSB is 50V/65536= 3.05mV. you just want to be able to maximize the resolution as the minimum output range is 50V.
    
 
    Other solution that you can consider is using the AD5391 with a gain amplifier (G=4) at the outputs. This solution maximizes the resolution of the DAC and the number of unused channels would be less.
    
 
    Best regards,
