Now use TLV2372(VDD=12V)to enlarge high level voltage of pwm from 3.3V to about 10.7V ，frequency range：1K--25KHZ
1.Is it necessary to connect a small capacitor in parallel with R1? if really need capacitor ,how much calculate capacitance value？
2.Is it necessary to connect a resistor in series between PWM_IN and positive input（pin3）？ if really need resistor ， how much calculate resistor value？
Thanks a lot!
