I am using set of 8 PCM1794a chips (4 mono right channel in parallel, 4 mono left channel in parallel) from DDDAC DAC design into the IVY I/V analog section. The output seems to drive into saturation with the current gain stage settings. I am unsure how the impedance of the 4 PCM1794a behave into the current gain stage of the IVY analog section. Any help would be appreciated as I seem to be at a loss for matching the current gain stage o the DAC chips.
Cheers,

Simply put, using four chips will result in 4x the output current. To get the same voltage output, you will want to use .25x the resistance.
