It's in the product description from TI, the TLC274 is 25nV/rtHz, the TL064
is 42nV/rtHz, not ultra-low by the standard of the AD797.

I have a choice of two op-amps for an audio application.

Which of the two, TL064 or TLC274 would generate the lowest internal
noise in a 300 - 3000 Hz audio application.

Thanks
