For AD9674, we need a differential driver for Gain+-, in datasheet figure38, there is reference design, but this design need an input from -1.6V to 1.6V, except a DAC, we need an OP amplifier to convert to bipolar output. and for this amplifier, need a negative power supply.
So I want to know is, is there a more simplified driver? Googled and found Linear has a design(dn454fa), can we use this design? for this design, Can we use op like AD8138? Is there any DAC recommend for this design? Thanks!
