Stereo AMP On TDA2003

[Ki-Di]

I do my small project (mini FM Radio Reciever + Builtin speakers with AMP) and found perfect AMP Schematic in internet for my AMP.

• R3,R6 - 220 Ohm
  
• R4,R5 - 2.2 Ohm
  
• U1,U2 - TDA2003
  
• SW - Micro ON/OFF Switch
  

PAD LIST

• P1,P2 - Left Chanel IN
  
• P7,P8 - Right Chanel IN
  
• P3,P4 - Left Chanel OUT
