Other Parts Discussed in Thread: INA149, OPA333, XTR111
Hi Support Team
I have a customer designing a circuit that is using two xtr117 being driven from a common dac. To make matters worse, the ground on the dac is referenced back to the VLoop ground. All bad, but I think I may have a solution. Can i use a high common mode difference amp powered individually off each XTR to translate from the dac output referenced to ground to the xtr input? Something like the ina149. Will design using a r2ri/o amp.
