WHY have Texas chosen NE5534 as an I/V converter followed by a LT1028

Please, explain for me the good reasons for this.

Obviously, for voicing. The PCM1792 is clearly so clean and clinical that some grungy stuff must be added to make it "musical".

These are design engineers, not audiophiles. The 5534 has lo noise, lo distortion but many stages inside. You can also alter compensation.

Maybe they should rename it and charge 10 times it's price
to keep some happy
One of the best for measurement; one of the worst for sound. It defines the soincs of much pro equipment.
Yes, but they also make more expensive parts. For the PCM1730 and 1738 (both of which have the same or better THD+N as the 1792!), they recommended the OPA627 or 5534.
I have been listening to a 627 for years and years, it's in my preamp, but it is buffered with a class A four-transistor emitter follower. I am not sure it really likes to deliver 7 mA peak current.

The mystery was that after a state of the art DAC connect an ancient opamp and THEN a low noise precision opamp! Can anyone tell me why?BrianL said:So, what's the mystery about the NE5534 in a TI datasheet?
TI makes this part; I just looked up their datasheet on the TI web site

I have spoken to people who have done extensive measurements on 5534 with AP. Apparently its main
sin is CM distortion and in inverting mode is one of
lowest distortion measuring OPA's.
It is interesting however, as BB always used to recommend
OPA627 for highest I-V performance.
