configuration lm358 741
Hi ...
I have a Saw-tooth 0-5 Volt Signal . I want to make output +5 Volt when Signal is higher than 3V and make output 0 Volt when input is lower than +3 volt .
I used Opamp 741 . I attach the schematic that i used . the output is Square Wave that is good but is between 1.5-4 Volt .
Why ? and How can i get 0-5 Volt Square Wave ?
I can fix the output by change the +Vcc to 6Volt and -Vcc to -1.4 Volt to have 0-5 Output But I don't Want to change my +Vcc and -Vcc pins and use 2 Power supply .
Should i change my opamp ? or My Design ? or Use Some IC Like LM311 to Compare Voltages ?
Regards .
