Dear all,

 

Thanks in advance!

 

Is there an opamp from ADI that is better than the LME49990 regarding distortion?

 

I attempted to build an ultra low distortion sine generator that can yield lower THD than -100dB but hit a wall.

 

THD is hovering between -95~ -100dB,  couldn't get any lower.

 

Please shed some light if you know the trick! 

 

Thank you again!
