Few years ago, when I've designed a fully balanced output filter-buffer for Creek Audio CD53, I've used THS4131 chips from TI with excellent results. Recently I've looked into the datasheet of a new "audio" chip OPA1632 from BB, which is now a part of TI. I could not believe it, but it looks like OPA1632 is the same chip as THS4131 (thought for half the price 🙂 ). All the parameters are the same, with one only exception - input current noise on OPA1632 is lower (and, obviously, these 2 chips are characterised somewhat differently according to the applications). Is it just a coincidence or is it a marketing strategy by TI, as Burr-Brown is a respected name for "audio" chips, and TI is somewhat lacks this image... ?!

... it's not totally unlikely. Burr-Brown breathe professional audio and Texas instruments more like consumer. Even B-B's datasheets looks more professionalx-pro said:
This can also be the case why TI hasn't skipped the B-B name. Compare PMI and AD. PMI vanished fast when AD bought that company.I agree that OPA1632 seems extreme, at least when it comes to numbers. Impressing distortion figures
HI
I have an SACD SONY SCD XB790, and I would like to replace the output by a OPA1632 or THS4131
The dac is a voltage output differential
How used these fully balanced op amp in this application ? but balanced output !!!
thx
