Other Parts Discussed in Thread: NE5532, OPA1612, OPA1678, TPA3251EVM
Would replacing the NE5532 with something like the OPA1612 and replacing the Op-Amp input and feedback resistors with a 2K instead of the 10K resistors lower the output noise of the EVM? I know this would reduce input impedance to the EVM but as long as my DSP board can still drive the EVM this seems like it should inject less noise.
