#158759 - More on unused opamp Responding to: ???'s previous message |
I would tie the output back to the negative (-) input and then connect the positive (+) input to mid supply bias level. If the mid supply bias level is not available then create it with two equal value resistors in a divider from supply to ground.
There is some informative literature on this subject. Try these links: http://www.planetanalog.com/showArtic...D=17603225 http://www.maxim-ic.com/appnotes.cfm/an_pk/1957 Michael Karas |
