If I have a MC33172 Opamp wired in a non-inverting configuration powered with 0 and +5V rails. What line items on the datasheet indicates how close the input can be to each rail?
Follow along with the video below to see how to install our site as a web app on your home screen.
Note: This feature may not be available in some browsers.
Then use a more modern "rail-to-rail" opamp.AND that would be why I asked. I will need to bump Vcc so I can get to +5V in and out.
I would bias the (+) input at half the supply voltage and connect the (-) input to the output to make this opamp a follower.If not all of the opamps in the package (ie., only one of two in a dual package) are used, what should be done to the inputs and outputs of the unsed opamps?
