TL082/TLO84?

There is a small difference.
I have noticed that a TL 082 works much better as a current to voltage converter, especially used by  current controlled amplifiers like the SSM 2024 etc. or DAC's.
If you use a TL 084 in that case you'll get big noise and no useable output (after some time).
I'll guess it has something to do with the built in frequency compensation.
But in most cases a TL084 is a very good choice.
If speed, low noise and Hi Z inputs are not required the LM 324 is also very good choice.
If my memory serves me well the LM324 's output also really goes to ground with a single voltage suply.
