I want to sum 4 channel output of ADA8282 "Radar receiver Path AFE: 4-Channel LNA PGA"
by op-amps and feed them to ARM cotrex-M7 microcontroller. though these channel are differential I want the final one as single ended, assume the bandwidth is 10MHz. I have seen some guideline from AD8333 "4 I/Q demodulator"
Since it told AD8333 output is in current format, I think this is not applicable in ADA8282 because it seems voltage output. :(
Is difference amplifier like AD8270 and 4830-2 will do the job nicely? any explanation will appreciated
can you specify architecture for me? I think it must not be hard but I'm not familiar with Op-Amp.
Any help will appreciated.
a question about difference amplifier added.
