Default Njm2068

I'm trying to estimate the noise performance of these amplifiers in a particular application.

The data sheet only specifies equivalent input noise voltage vs. source resistance (EINV). The test method is specified as "JIS A".

Does anyone know what the weighting characteristic of "JIS A" is?

I'd like to convert the EINV to nV/rtHz between 100Hz and 50kHz.

Here is a bit from NJM2114 datasheet - it shows a very similar graph for A-wtd noise and has got a noise density graph as well.

Cheers
