Hello Bordodynov, thanks so much for reply. So I have to remove that capacitor, and then connect directly pin5 to GND. Right ?No, this is not correct. The voltage on the substrate will float capacitance of the parasitic diode can reach a maximum value, and this will worsen the frequency parameters. If you have unipolar power, then connect the substrate to earth (GND). Why don't you want to follow the manufacturer’s order?
