Hello

i am using NI DAC (6723) to drive QSC RMX 4050HD Power amplifier (PA) having input impedance of 10 kohm. I am generating 1-5KHz sinusoidal signals from my DAC.

1- I need some isolation & signal smoothing b/w DAC & 2kWatt PA.

2- Secondly, NI DAC has current limitation of 5mA/channel. I also desire to boost this capacity to say (10mA/channel) with some IC b/w DAC output & PA input.

Can any one kindly suggest some type of analog isolation IC/transformer which can do this job?

Thanks

Best Regards
asim
