TDA2003 opamp question? Answered
Hello i have some questions about the opamp TDA2003.
1.In the picture bellow the R1 and R2 make the gain for opamp .Gain=R2/R3=220/2.2=100. It's of if i replace the R2 with 2k resistor and R3 with 200 Ohms resistor ??? The gain still the same but i dont know if it still ok ??
2.What the C2(470uF) do in this schematic, what will happend if i replace it with a 100uF capacitor ?
Thanks for advance!
sorry for my bad English !
