I am interested in using the AD8556.In the data sheet there is no specification regarding offset settings. - Especially I want to know the step size of output offset in respect to second stage gain.- Likewise, what is the factor of DAC-value to the summing of output of first gain stage?- What is the formula to calculate output offset voltage (to ground) when supply is 5V?- for acheiving high bandwidth is it advisable to use higher gain in first stage and use lower gain in second stage (we need approximately G= 400)?
Also I want to know, for how long approximately this huge programming current will flow to blow one fuse?
All this needed info is missing in the dataq sheet!I suppose that you revise it with that information.
