Has anybody tried these for audio? The 1/f noise spec looks very good, so potentially a good RIAA amplifier candidate
From studying the datasheet, several things would make me wary of these in an audio application. They do look to be aimed at precision DC circuits.
There's no PSRR plot, the small signal FR plot shows an inexplicable 'suck-out' of a couple of tenths of a dB between 1k and 10k, and the input voltage noise vs freq plot has a worrying spike around 65kHz. This latter might be related to the switching frequency for compensating for the input offset and 1/f noise.
