[sdiy] Testing OTA performance

[Paul Brown]

Hey SDIYers,
	I am testing some parameters for various OTA's.  The OTA's being  
tested are the 3080, LM13700, JRC13700, and JRC13600.  I have  
measured the control current versus gain, and I also want to measure  
the noise output of the OTA's.  I am thinking about hooking a large  
amplifier up to the output of the OTA, with no input into the OTA,  
and seeing how flat that output signal is.  Are there any better  
ideas out there?  Also, any ideas on how to measure the distortion of  
these OTA's?

Thanks in advance,
Paul
