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?
