Has anyone A/B compared the AD8620 to using two separate AD8610 opamps, in the PIMETA?
Tangent has the best price for either of these. Putting two singles on a BrownDog adapter is marginally more work than soldering a dual, and at his prices the cost comparison is basically a wash.
My prejudice is that any dual opamp is compromised, but this may be unfounded. In PPAv2, each single opamp gets its own power circuit, but in the PIMETA they're two kids in the same bath, perhaps very similar distortion issues whether they share a BrownDog adapter or a single chip?
