Hello…. i’m doing a project,in which i shall be operating the atmega-32 uc such that the OC2/D7 pin is the output. The OC2 o/p will be used to drive an ultrasonic transmitter,and my tests reveal that the ultrasonic transmitter needs atleast 3V for sufficient range.
Can you tell me what the output voltage of the OC2 pin is ? also,if it is less than 2 V,can u suggest some way of pulling it up ? Can i use a opamp? If yes,which one...bcoz i guess the slew rate will have to be considered,since OC2 frequency will be 40 Khz.
