i am using this amplifier to amplify the weak signals from TDA7000,i think its audio output will be 75mV,so if the input capacitor capacitor value is 2.2μF(16V),i think there will be no problem!
what do u say!!!!

READ YOUR OTHER THREAD ABOUT THIS SAME PROBLEM AND YOU WILL HAVE THE ANSWER!!

IN RF or AUDIO circuits it is best to stick with the bill of materials, so 16 VOLT CAP WILL NOT WORK FOR THE 3 VOLT THAT IT CALLS FOR SINCE IT IS PART OF THE AF INPUT!!!

 

but 3v cap is not available,is there any alternative for this ,please help me guys

 

what if i use a ceramic capacitor instead of electrolytic cap for C1 in TDA2003 schematic

 

Hello,

A non-polarized capacitor like MKM or polystyrene will work.

thank u very much
