Hi. Without signal chip select in microcontroller don't grabed pins (use 4 DACes ) and scheme is asserted manager i don't use AD5556. For future design i have in mind AD5556.
Can the Rofs pin of the AD5556 be left unconnected when used in unipolar two-quadrant mode? It appears that this would increase the feedback resistance from 5kΩ to 10kΩ. Would this then also increase the output range from 0V - Vref to 0V to 2Vref?
You may want to check out the AD5546/AD5556. It can be used in parallel mode similar to the AD7840.
Would you have any other specifications that you would need to take note of? Could you share what is your target application? Knowing these, we can pick DACs that will better suit the application that you have. I have made a list of DACs bel…
If your voltage output should be around +-10V I would recommend use one opamps to increase your voltage reference to +10V.
this will keep your noise levels quite low selecting the appropriate resistance.
In a second stage you can use a multiplying…
The data sheet says a 20pF capacitor is generally adequate for the compensation. The compensation capacitor prevents ringing and instability at the output of the DAC. If you want to compute for the capacitance, you can use the equation below. Note…
I see that the operating temperature of the AD5553 is -40 to 85C. Is that air temperature around a mounted device on a standard board or is that case temperature?
The operating temperature ranges seen on the data sheets are…
