i wan't to measure the maximum and minimum output swing of a Comparator. I'm using the circuit which you can find attached.
However, since the Output of the Comparator (TI LM2903) is open drain, I need the Pull up. I also need the Load Resistor to measure the output swing with a load.
To trigger the Comparator, I'm using a +-1V voltage with a given 0V reference voltage.
With the -1V at the non-inverting input I get -9.8V at the output, but with +1V I only get 4.9V because of the voltage divider (Pullup to Load 1:1).
How can i achieve a full positive output swing to nearly 10V?
