Open loop gain measurements of NE5534 / NE5532 / LM318 from various manufacturers

[SirPaulGerman]

I know this is a stupid question, which manufacture makes the better 5534 and 5533 ?

 

[ejp]

Nobody makes 5533, for many decades.

 

[rsavas]

I have one, signetics of course
I do not think it really matters who the manufacture is. I only recall two mfg for 5533, signetics and exar.

 

[SirPaulGerman]

Nobody is making the 5533 and the 5534 anymore ?

 

[rsavas]

How about look on mouser or Digi-Key

 

[SirPaulGerman]

Only 2 active manufactures on Mouser
TI and Osemi

Back to those ol measurements: did anybody compare them with the data sheets of those devices? Is there a reason why those measurements should be done rather then looking up the data sheet?
The data sheet gives the average curve, so to say, while the measurement uses just one sample, which may be an outlier.

Has anyone here ever tested the new Chinese 5532s and 5534s? LCSC has them. The brands are HGSEMI and Cosine. I've compared the datasheet of the Cosine COS5532 to the ones from TI, OnSemi and JRC. The specs are almost identical, except for the input voltage. They specify a maximum of +-18v.

Nobody is making the 5533. 5534 is still a jellybean part.
