The AD5544 is recomended for single supple operation. However the recomended configuration uses an inverting mode op-amp to do the I to V conversion, which means that a negative rail is required for the op-amp; there goes the single supply operation. I believe this configuration is recomended to minimise drift over temperature by using the internal Rfb in the DAC. I could configure the op-amp as non-inverting, but then I would not be using the internal Rfb in the DAC. Is there a recomended method for configuring the AD5544 and its I to V op-amp for use on a single supply?
Hi, the AD5544 do not operate in single supply operation, there must be an errata in the documentation for this part. Could you tell us where did you get this information from in order to edit it and avoid future misunderstandings?
The single supply operation with current output DACs is posible using the AD54XX family. Also Quad NanoDACs as the AD5665R allow this operation.
Sorry for the trouble caused.
